Foreword

Australian Tube Mills is one of the world’s premier producers of welded steel tube and pipe for structural, mechanical and low pressure reticulation applications. For many years, Australian Tube Mills has been at the industry forefront with numerous innovations delivering significant value to a wide range of key industries. With manufacturing facilities strategically located in Australia (Brisbane, Newcastle, Melbourne and Perth), Australian Tube Mills is effectively placed to supply high quality tubular steel products to markets in Australia, New Zealand, South Pacific and SouthEast Asia. Australian Tube Mills’ innovative approach to the development of tubular products has been noted by various industries for many years. This has included the introduction and ongoing push of higher strength RHS and Pipe products which reduce weight and cut costs for endusers. Strength enhancements began with Grade C350L0 (“TruBlu”), then Grade C450L0 (“GreensTuf”) and DuraGal® and now C450PLUS® (previously DualGrade® C350L0/C450L0) products. Australian Tube Mills were the first to develop and promote these grades into Australian Standards and its market areas and now offer the largest range of C450PLUS® sections – not only in Australia but across the world. Development of tubular shapes has also been an important strategy for Australian Tube Mills. Specific shapes (some of which carry patents and trademarks) were developed for defined industries and include the SiloTube, UniRail, StockRail and Architectural sections. Limited rollings of other forms of hollow sections can be supplied on a special order basis.

Compared to other steel products, the worldwide consumption of welded tubular steel products is significantly increasing. The main reasons for this outcome is due to the aesthetics, engineering efficiencies, cost-effectiveness, increased specifier/end-user awareness and the high valueadding inherent with tubular products. This has now firmly positioned Australian Tube Mills as the preferred tubular supplier within many industries. Quality products, people and service sets Australian Tube Mills apart from its competitors.

Acknowledgements Australian Tube Mills gratefully acknowledges the assistance provided by the Australian Steel Institute (ASI) – previously the Australian Institute of Steel Construction (AISC) – for permitting the use of their “Design Capacity Tables” text and format in the development of various parts of this publication. Additionally, Australian Tube Mills wishes to acknowledge the detailed contributions from the following: Russell Watkins of Australian Tube Mills for writing, generating and checking the text, tables and graphs used in this publication; OneSteel’s marketing services team for artwork and coordination; and Nick van der Kreek at Australian Tube Mills for checking and updating various aspects of this publication.

Apart from material improvements, Australian Tube Mills’ plants also produce different types of coating systems for tubular products. Revolutionary primer-paint systems were developed with industry participation to protect hollow sections from rust during warehouse storage, transportation and fabrication as well as offer a smooth clean work surface during and after fabrication. Australian Tube Mills now supplies the largest range of welded tubular steel products in Australia which vary in shape, grade and finish.

Preface

The “Design Capacity Tables for Structural Steel” (DCT) suite of publications from the Australian Steel Institute (ASI) – previously the Australian Institute of Steel Construction (AISC) – has been commonly used by design engineers for at least a decade. The actual origin of these publications goes back to 1969 when the Safe Load Tables (SLT) was published by AISC (at the time) for the then permissible stress based steel structures Standards AS CA-1 and subsequently AS 1250. The SLT was published in six editions (the last edition being in 1987) with both hot-rolled “open” sections (e.g. UB, UC, PFC, etc) and structural steel hollow sections (CHS, RHS and SHS) included in its contents.

availability. Various manufacturers also complicated the situation by producing their own versions of the DCTHS even though they had a smaller product/size range. Subsequent market studies by Australian Tube Mills revealed that there was growing specifier and industry frustration from the numerous but fragmented publications available that attempted to describe the total range of hollow sections compliant with Australian Standards. Market feedback also indicated some level of confusion with what sizes were available in various grades. There was no ready answer to this frustration and confusion – unless, of course, a single manufacturer could confidently supply a total consistent range of hollow sections.

The release of AS 4100 Steel Structures in 1990 to supersede AS 1250 saw a change in design philosophy from permissible stress to limit states design principles. Such a change prompted the revision of the SLT to manifest itself as the DCT. The first edition of the DCT had an overall format which was similar to the sixth edition of the SLT and included both open and hollow sections. However, due to the growing popularity, increasing range and innovation of hollow section construction, the DCT was effectively split in 1992 with the release of the “Design Capacity Tables for Structural Steel Hollow Sections” (DCTHS) which only considered tubular members. Thereafter, a second edition of the DCTHS was released in 1999 entitled “Design Capacity Tables for Structural Steel – Volume 2: Hollow Sections” (DCT-v2:HS).

As part of its ongoing Sales & Marketing strategies, and after much analysis, Australian Tube Mills are undertaking various initiatives to significantly grow the tubular market with a substantial increase in product range and technical support. Prior to this initiative, one of the limitations with tubular construction was the restricted range of large readily available hollow sections that are fully compliant with Australian Standards. For RHS/SHS this was seen to typically “top out” at 250 x 250 SHS with thickness up to 9 mm thick. The situation with CHS was slightly different with the availability of larger “down-graded” line-pipe though there were some issues reported on the compliance of such products to the structural requirements of AS/NZS 1163 Grade C350L0.

While somewhat of a challenge, the aim of the DCT-v2:HS (and preceding DCTHS/DCT) was to provide current information on hollow sections available from various manufacturers. However, at the time of publication, the consolidated product range listing from each of the manufacturers was disjointed and not reflective of available sections. Even though the DCT-v2:HS listed a large range of hollow sections, this positive aspect was negated by imprecise information on product

The ability to supply a full range of structural steel hollow sections coupled with the ability to ease industry frustration from the lack of consolidated correct information of such sections also sees Australian Tube Mills providing a large array of technical/marketing media (i.e. literature and software). Part of the media includes this DCTHS which is based on AS 4100 –1998. In order to embrace the acceptance level of the previously published industry document, this

Preface (continued)

DCTHS follows the same format as the ASI/AISC DCTHS. This means that the Parts of this publication follow the same numeric sequence as those in the ASI/AISC DCTHS and AS 4100. The tabulated data and much of the text in this publication also follows the same format and sequence as the ASI/AISC DCTHS which now makes it a ready companion to the DCT for hotrolled “open” sections. Hence, if readers are familiar with the current ASI/AISC DCTs they will also be familiar with this publication. Whilst based on the ASI/AISC DCTHS, some minor revisions, corrections and updates were incorporated in this publication as well as recognition of the changed “loading” Standards to AS/ NZS 1170 and other related Standards. Also, readers will note that this publication is produced in “landscape” format – i.e. the width of the page is the longer dimension. The rationale behind this modification followed industry surveys that noted the generally published “portrait” format did not suit publications substantially containing landscape tables. Consequently, this and several other Australian Tube Mills publications have been produced in landscape format. For additional information, readers should also refer to page (ii) for the appropriate use of this DCTHS. As a complementary design aid to this publication, Australian Tube Mills has also produced a simple calculator for structural steel hollow sections designed to AS 4100. Called TubeComp®, the software provides much of the information contained in this publication with just four (4) “clicks of a mouse”. The data screens of TubeComp® are dynamically updated and can provide

exact values of design capacities for effective lengths not listed in the tables of this publication without the need for linear interpolation or extrapolation. TubeComp®, like this and other publications, are freely available from Australian Tube Mills by using the contact details noted below. It is interesting to note that after nearly twenty years since the release of the first DCTHS, the same basic team involved in the first document has been brought together to develop this publication. This team includes engineers for computations, content and project management as well as graphic designers. Accordingly, we trust this publication is of value to designers of hollow section construction and would appreciate any feedback on its adequacy or ways to refine it. May your designs in tubular construction be fruitful ones! Arun Syam Editor & Tubular Development Manager Australian Tube Mills

Part 1 INTRODUCTION 1.1 General 1.1.1 Steel Structures Standard The tables in this publication have been calculated in accordance with the Australian Standard AS 4100 –1998 Steel Structures. As far as possible, the notation and terminology used are the same as those adopted in that Standard. Cold-formed hollow sections manufactured in accordance with Australian Standard AS/NZS 1163:2009 Structural Steel Hollow Sections are included within the scope of AS 4100. Extensive research [1.1,1.2,1.3] undertaken over a number of years has confirmed that cold-formed hollow sections compliant with AS/NZS 1163 meet the inherent requirements of AS 4100. Cold-formed hollow sections may also be designed to AS/NZS 4600:2005 Cold-Formed Steel Structures which is outside of the scope of this publication.

1.1.2 Reference Standards “AS 1074” refers to AS 1074 –1989 Steel tubes and tubulars for ordinary service

A brief list of the Tables’ contents is provided in Section 1.5. It should be noted that the main tables listing design capacities and other member information are placed at the end of the initial text portion of each Part of this publication. The main tables will generally be listed within a numerical sequence – e.g. Table 5.1 series (Maximum Design Loads for Simply Supported Beams with Full Lateral Restraint), Table 5.2 series (Design Section Moment and Web Capacities), Table 5.3 series (Design Moment Capacities for Members without Full Lateral Restraint), etc. Any table listed in the (initial) text portion of each Part of this Publication will have a “T” before the Table number – e.g. Table T2.1 in Section 2.2.

1.2

Range of Structural Steel Grades and Sections

The Tables contain information on the currently available (at the time of publication) structural steel hollow sections supplied by Australian Tube Mills (ATM) which fully comply with AS/NZS 1163. Section 2 should be consulted for further details on the structural steel hollow sections considered in the Tables. Reference should also be made to the Australian Tube Mills Product Availability Guide (PAG) for general information on the availability of the listed sections and associated finishes.

“AS 4100” refers to AS 4100–1998 Steel structures “AS/NZS 1163” refers to AS/NZS 1163:2009 Cold-formed structural steel hollow sections “AS/NZS 1170” refers to AS/NZS 1170:2002 Structural design actions “AS/NZS 1554.1” refers to AS/NZS 1554.1:2011 Structural steel welding – Welding of steel structures “AS/NZS 2312” refers to AS/NZS 2312:2002 Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings “AS/NZS 4600” refers to AS/NZS 4600:2005 Cold-formed steel structures

1.3

Units

The units in the Tables are consistent with those in the SI (metric) system. The base units utilised in the Tables are newton (N) for force, metre (m) for length, and kilogram (kg) for mass. Where noted, stress is expressed in megapascals (MPa). With some minor exceptions, all values in the Tables are rounded to three (3) significant figures.

Part 1 INTRODUCTION 1.4

Limit States Design using these Tables

AS 4100 sets out the minimum requirements for the design, fabrication and erection of steelwork in accordance with the limit states design method and follows a semi-probabilistic limit state approach presented in a deterministic format. Definition of limit states – When a structure or part of a structure is rendered unfit for use it reaches a ‘limit state’. In this state it ceases to perform the functions or to satisfy the conditions for which it was designed. Relevant limit states for structural steel include strength, serviceability, stability, fatigue, brittle fracture, fire, and earthquake. Only two limit states are considered in the Tables – the strength limit state and, where applicable, the serviceability limit state. Limit states design requires structural members and connections to be proportioned such that the design action effect (S*) resulting from the design action (W*), is less than or equal to the design capacity (qRu) i.e. S* ) qR u Design action or design load (W*) is the combination of the nominal actions or loads imposed upon the structure (e.g. transverse loads on a beam) multiplied by the appropriate load combination factors as specified in AS/NZS 1170 (Structural design actions). These design actions/loads are identified by an asterisk ( * ) after the appropriate action/load (e.g. W*L is the maximum design transverse load on a beam). Design action effects (S*) are the actions (e.g. design bending moments, shear forces, axial loads) calculated from the design actions or design loads using an acceptable method of analysis (Section 4 of AS 4100). These effects are identified by an asterisk ( * ) after the appropriate action effect (e.g. M* describes the design bending moment). Design capacity (qRu) is the product of the nominal capacity (Ru) and the appropriate capacity factor (q) found in Table 3.4 of AS 4100. Ru is determined from the characteristic values and specified parameters found in Sections 5 to 9 of AS 4100. For example, consider the strength limit state design of a simply supported beam which has full lateral restraint subject to a total transverse design load (W*) distributed uniformly along the beam.

For flexure, the appropriate design action effect (S*) is the design bending moment (M*) which is determined by: M* = W * L

8

where L = span of the beam. In this case the design capacity (qRu) is equal to the design section moment capacity (qMs ), given by:  qMs = qfy Ze where q = the capacity factor fy = yield stress used in design Ze = effective section modulus To satisfy the strength limit state, the following relationship (equivalent to S* ) qRu) is used: M* ) qMs The maximum design bending moment (M*) is therefore equal to the design section moment capacity (qMs), and the maximum design load is that design load (W*) which corresponds to the maximum M*. (It should be noted that other checks on the beam may be necessary – e.g. shear capacity, bearing capacity, etc). When considering external loads, in the context of this publication, the maximum design load (W*L ) given in the relevant table must be greater than or equal to the imposed design load (W*). Where applicable, the Tables give values of design capacity (qRu) and maximum design load (W *L ) determined in accordance with AS 4100. When using the Tables, the designer must determine the relevant strength limit state design action (W*) and/or corresponding design action effect (S*) to ensure that the strength limit state requirements of AS 4100 are satisfied. Where relevant, other limit states (e.g. serviceability, fatigue, etc) must also be considered by the designer. Some useful information for checking the serviceability limit state is included in the Tables.

Range of Structural Steel Grades and Sections

These Tables cover the full range of structural steel hollow sections supplied by Australian Tube Mills manufactured in accordance with AS/NZS 1163. The section sizes and their respective grades listed in the Tables include: AS/NZS 1163 Grade C250L0 Circular Hollow Sections (CHS) AS/NZS 1163 Grade C350L0 Circular Hollow Sections (CHS) AS/NZS 1163 Grade C350L0 Rectangular Hollow Sections (RHS) (‘small’ sizes only) AS/NZS 1163 Grade C450PLUS® RHS AS/NZS 1163 Grade C350L0 Square Hollow Sections (SHS) (‘small’ sizes only) AS/NZS 1163 Grade C450PLUS® SHS The grade designation (e.g. C450L0) is based on the nominal minimum yield strength of the steel (in MPa). The prefix ‘C’ is used before the value of the nominal yield strength of the steel to indicate that the section is cold-formed. It should be noted that AS/NZS 1163 only considers cold-formed structural steel hollow sections. The suffix ‘L0’ denotes impact properties at 0°C as specified in AS/NZS 1163. Hollow sections rated with impact properties such as L0 are not only important in lower temperature environments but also for welded structures subject to dynamic loads. This becomes much more important for hollow sections with larger thickness (i.e. t * 6.0 mm). AS/NZS 1163 Grade C450PLUS® RHS/SHS comply with the strength and elongation requirements of both Grade C350L0 and C450L0. The key mechanical properties of C450PLUS® are covered in Section 2.2 and a further description of C450PLUS® is given in Section 2.4. Where relevant, C450PLUS® RHS/SHS are designed as AS/NZS 1163 Grade C450L0 sections in these Tables to capitalise on the higher strength benefits of this steel grade – see Section 2.4.2. C450PLUS® are registered trademarks of Australian Tube Mills. Further general information on the availability of the sections listed in the Tables is noted in Section 2.7.

Hollow sections supplied by Australian Tube Mills are manufactured by cold-forming and highfrequency Electric Resistance Welding (ERW). The ERW process allows cold-formed hollow sections to be welded at ambient temperatures without subsequent stress relieving. However, the Tables only apply to those hollow sections manufactured in accordance with AS/NZS 1163 and supplied by Australian Tube Mills. Specifiers should also note that hollow sections not complying with AS/NZS 1163 may be required to be down-graded in yield stress, tensile strength and other mechanical properties when designing to AS 4100 and welding to AS/NZS 1554.1 – see Section 2.6. To ensure the assumptions, product benefits and quality of structural steel hollow sections considered in these Tables, designers should specifically nominate AS/NZS 1163 compliant product in their specifications and general notes. Such wording may be: Unless Noted Otherwise – CHS to comply with AS/NZS 1163–C350L0 RHS/SHS to comply with AS/NZS 1163–C450L0 Note, for SHS with overall dimensions of 50 x 50 and smaller (and equivalent perimeter RHS), ATM typically supplies these sizes in Grade C350L0 to AS/NZS 1163. However, these sizes are available ex-rolling to AS/NZS 1163-C450L0 subject to minimum order requirements. By specifying AS/NZS 1163–C450L0 RHS/SHS in the general notes and specifications it will also signal the fabricator to use typically available, prequalified higher strength welding consumables (i.e. E49/W50). This is generally reinforced by the welding part of the specification and general notes which flags the welding consumables to be E49/W50 – unless noted otherwise – as this is typical practice. However, should designers not utilise the higher strength benefits of C450PLUS® and only use its C350L0 properties, this can be indicated outside of the general notes and specification at the appropriate drawing arrangement or detail.

Part 2 MATERIALS It should be noted that Australian Tube Mills also supplies AS/NZS 1163–C250L0 CHS and, if used and specified, they can also be flagged as such in the relevant part of the engineering/ workshop drawings, material lists and/or bills of quantities with the default Standard and grade specification as noted above. The importance of “L0” impact properties cannot be understated (as noted in Section 2.1) and has to be included in the grade designations of general notes, specifications and other points of steel grade reference. In conjunction with the above structural steel hollow section Standard and grade designations, further information on the appropriate specification of structural steelwork can be found in Ref.[2.1] or by contacting Australian Tube Mills.

NOTE: See Section 2.4 for a definition of C450PLUS® and its use in these Tables. More detailed information on the strengths and other mechanical properties of these steels can be found in Table 2.1 of AS 4100, AS/NZS 1163, other ATM product guides or by contacting ATM (by the contact details noted at the bottom of the page).

The masses given in these Tables are based on a steel density of 7850 kg/m3, the nominal section size and standard corner radii (see Section 3.2.1.2). In practice the tabulated values are affected by rolling tolerances and actual corner shape. Masses per metre listed are for the sections only, and do not include any allowances for cleats, end plates, weld metal, etc.

2.4 Grades 2.4.1 Circular Hollow Sections (CHS) Australian Tube Mills (ATM) offers CHS in two AS/NZS 1163 grades: C250L0 and C350L0. The Grade C350L0 products provide a more comprehensive range of sections for structural applications and should be commonly specified. ATM also provide CHS/Pipe products which comply with AS 1074 and AS/NZS 1163–C250L0 for structural and low pressure piping applications. As the sizes supplied in the C250L0 CHS range are used in structural applications, they are also offered as Structural CHS by ATM.

Part 2 MATERIALS 2.4.2 Rectangular/Square Hollow Sections (RHS/SHS) and C450PLUS® Due to the nature of manufacturing cold-formed hollow sections, RHS/SHS generally have higher strengths and lower elongations (from tensile tests) than CHS manufactured from the same type of feed-coil. This is basically due to the additional cold-working RHS/SHS receive during the sizing and finishing stages of shape formation. Consequently, from the three basic strength grades noted in AS/NZS 1163, CHS are generally supplied in grades C250L0 and C350L0 whereas RHS/SHS are supplied in the higher strengths of grades C350L0 and C450L0. Australian Tube Mills (ATM) have always been at the forefront in utilising higher strength hollow sections both in Australia and internationally. This was previously seen by ATM’s push to use Grade C350L0 for CHS, Grade C450L0 for RHS/SHS (the “GreensTuf” range) and now by offering the C450PLUS® RHS/SHS across a wide range of pre-coated and uncoated products. The name C450PLUS® is derived from satisfying two key mechanical properties from tensile tests – strength and elongation. These properties undergo opposing effects during manufacturing. As noted above, it is widely known that the cold-forming process increases material strengths of welded cold-formed hollow sections. However, the elongation requirements of the material (a reflection of ductility) generally do not increase with strength. This is best illustrated by the following extract from AS/NZS 1163: Structural Steel Hollow Sections – Table T2.3: Tensile test requirements for RHS/SHS from Table 6 of AS/NZS 1163

NOTE: These elongation limits apply to the face from which the tensile test is taken.

The above table shows that higher strengths are developed in Grade C450L0 products and higher elongation is attained with Grade C350L0 products. C450PLUS® satisfies all the higher values of these key mechanical properties (shaded in Table T2.3 and also summarised in bold in the last row of that table).

supplying C450PLUS® RHS/SHS include: Grade C450L0 by itself may not perform well if the hollow section is bent to a tight radius during fabrication (e.g. corners in gate frames, etc). Excess straining sometimes produces section failures. Experience has shown that Grade C450L0 products which possess the C350L0 elongation requirements can be adequately formed in these situations. Structural steelwork drawings sometimes nominate C350/C350L0 as the default (i.e. “unless noted otherwise”) grade for RHS/SHS. It is often perceived that C450L0 is a new and less readily available grade. This perception is not true as Australian Tube Mills has been supplying a large range of C450PLUS® RHS/SHS in pre-coated and uncoated finishes for some time. However, there remains some specifiers and endusers who wish to use C350L0 RHS/SHS. C450PLUS® can fulfill their requirements as well as the requirements of those who wish to specify/use higher strength C450L0 and its inherent advantages. Dual-stocking of grades for a particular section is costly. If the same section can comply with the requirements of both the commonly specified lower strength grade and the structurally efficient higher strength grade, a lower cost product will be available to the specifier and end-user. In order to capitalise on the benefits of C450PLUS®’s higher strength properties, the Tables contained in this publication consider C450PLUS® RHS/SHS to be designed with the strength properties of AS/NZS 1163 Grade C450L0 – i.e. fy = 450 MPa and fu = 500 MPa. As noted in Section 2.1, impact properties such as “L0” are not only important for low temperature applications but very important for welded members subject to dynamic loads. This is particularly so for thicker hollow sections. Hence, “L0” impact rated hollow sections, which is satisfied by all of ATM AS/NZS 1163 compliant structural hollow sections, should always be specified. Further information on AS/NZS 1163 Grades C250L0, C350L0 and C450PLUS® can be found in the Australian Tube Mills’ (ATM) Product Manual. These and other publications and software can be obtained freely from www.austubemills.com or by contacting ATM via the details noted at the bottom of the page.

Mill Surface Finishes

It is commonly recognised that pre-primed and pre-coated hollow sections provide considerable benefits and savings for fabrication construction as these sections are coated either prior, during or immediately after the tube forming process. Australian Tube Mills are regarded as being innovative in various mill finishes for many years and offer tubular products in the following surface finishes: DuraGal®, SupaGal®, (semi-continuous) hot-dip galvanized, primer-painted, oiled, and NOP (no oil or paint) coatings. ATM’s galvanized coatings comply with AS/NZS 4792. It should be noted that due to manufacturing limitations, surface finishes can vary with shape and size of hollow section. Further information on Australian Tube Mills’ (ATM) surface finishes can be found in the ATM Product Manual. These and other publications and software can be obtained freely from www.austubemills.com or by contacting ATM via the details noted at the bottom of the page. AS/NZS 2312 also provides useful information on this topic.

Hollow Sections Not Compliant with AS/NZS 1163

A key aspect of design within the provisions of a national steel structures Standard as AS 4100 is the inclusion of cold-formed hollow sections. This situation is highly dependent on the integrity of the supporting material Standards. One such material Standard is AS/NZS 1163 Structural steel hollow sections. AS/NZS 1163 has been developed to reflect the way cold-formed hollow sections have been manufactured, specified, fabricated and subsequently used in Australia. This includes taking account of the enhancement in strength due to cold-forming, superior product tolerances (including dimensional limits and the supply of minimum cross-section material as assumed in design), ductility, weldability and resistance to impact loads. Designers and specifiers should be very wary of the substitution of AS/NZS 1163 product by either unidentified product or specific product complying with other inferior international Standards which do not deliver the full range of AS/NZS 1163 product requirements. AS 4100 states that hollow sections not complying with AS/NZS 1163 must be tested and checked for compliance. Non-conforming or unidentified hollow sections must be down-rated to a design yield stress of 170 MPa and a design ultimate strength of 300 MPa. Though AS 4100 is a key Standard for the design, fabrication and erection of steelwork, other important Standards are also used to produce the completed structure that is to be eventually fit for purpose. The other important Standards for structural steel hollow sections include welding, painting and galvanizing which, in the case of structural steel hollow sections, are also dependent on compliance with AS/NZS 1163. Additionally, as noted in Sections 1.1, 1.2, 2.1 and 2.2, the use of these Tables is also based on hollow sections complying with AS/NZS 1163.

General

The section property tables include all relevant section dimensions and properties necessary for assessing steel structures in accordance with AS 4100. The AS/NZS 1163 structural hollow sections included in these tables are: Circular Hollow Sections Grade C250L0 Circular Hollow Sections Grade C350L0 Rectangular Hollow Sections Grade C350L0 (smaller sizes as noted in the Tables) Rectangular Hollow Sections Grade C450PLUS™ Square Hollow Sections Grade C350L0 (smaller sizes as noted in the Tables) Square Hollow Sections Grade C450PLUS™ C450PLUS™ RHS/SHS are designed as Grade C450L0 – see Section 2.4.2 for further details.

The torsional constant (J) and the torsional modulus constant (C) for square and rectangular hollow sections are defined as follows: £ h ¥ J = ²t 3 2 kA h´ ¦ ¤ 3 £t 3 h 2kA ¥ h´ ² 3 ´ C = ² ² k ´ ´ ²

For each group of structural hollow section the Tables include: Dimensions, Ratios and Properties Properties for Design to AS 4100 These parameters are considered in Tables 3.1-1 to 3.1-6 inclusive.

3.2.1 Dimensions, Ratios and Properties The Tables give standard dimensions and properties for the structural steel hollow sections noted in Sections 2.1, 2.7 and 3.1. These properties, such as gross cross-section area (Ag), second moments of area (lx, ly), elastic and plastic section moduli (Zx, Sx, Zy, Sy) and the torsion constant (J) are the fundamental geometric properties required by design Standards. It should be noted that Clause 5.6 of AS 4100 indicates that the warping constant (lw) for hollow sections may be taken as zero. Additionally, the external surface area of the hollow section – as used in estimating quantities of protective coatings – is also considered within these Tables.

5.2 Design Section Moment and Web Capacities 5.2.1 General For RHS and SHS, the 5.2 Table Series – i.e. Tables 5.2-1 to 5.2-4 – contain values of design section moment capacities about the principal x- and y-axes (qMsx , qMsy) and the design shear capacity (qVv) for shear forces acting in the principal y-axis direction (i.e. for RHS/SHS bending about the x-axis) and in the principal x-axis direction (for RHS only). These values provide the basic information necessary for checking shear-bending interaction. The Tables also provide

listings of the design torsional section moment capacity (qMz) for RHS and SHS. The maximum segment length for full lateral restraint (FLR) for RHS is also listed. FLR values may be used to ensure appropriate spacing of restraints so that the design section moment capacity can be achieved for bending about the x-axis. The Tables also provide values of design web bearing capacities. Due to there being no specific CHS design provisions for web bearing in AS 4100, CHS are not considered in the 5.2 Table series though design section capacities (e.g. qMsx, qVv and qMz) can be found in the 8.1 and 8.2 Table series.

5.2.2 Method 5.2.2.1 Design Section Moment Capacity The design section moment capacity (qMs) is determined from Clauses 5.1 and 5.2.1 of AS 4100 using: qMs = qfy Ze where q = 0.9 (Table 3.4 of AS 4100) fy = yield stress used in design Ze = effective section modulus (see Section 3.2.2.2) For RHS, design section moment capacities are listed for bending about both principal axes. These actions are split into two separate tables – the type (A) table for bending about the x-axis (e.g. Table 5.2-2(1)(A) for Grade C450L0 (C450PLUS®) RHS lists qMsx) which is immediately followed by the type (B) table for bending about the y-axis (e.g. Table 5.2-2(1)(B) for Grade C450L0 (C450PLUS®) RHS lists qMsy). Due to SHS being doubly-symmetric, the SHS tables (i.e. Tables 5.2-3 and 5.2-4) only consider design section moment capacities about the x-axis. For RHS bending about the x-axis, the design member moment capacity (qMb) equals the design section moment capacity (qMs) for members which have full restraint against flexural-torsional buckling (see Section 5.1.3). For SHS bending about the x-axis and RHS bending about the y-axis, flexural-torsional buckling does not normally occur so qMb equals qMs (refer section 5.1.3).

Part 5 MEMBERS SUBJECT TO BENDING 5.2.2.2 Segment Length for Full Lateral Restraint (FLR) The Tables only consider RHS bending about the major principal x-axis to be susceptible to flexural-torsional buckling. For such sections, a beam segment with full or partial restraint at each end may be considered to have full lateral restraint if its length satisfies Clause 5.3.2.4 of AS 4100, i.e.

However, `m = -0.8 may be used for segments with transverse loads (as in the case of the (A) series tables in Tables 5.1-3 and 5.1-4 for RHS). Alternatively, `m may be taken as the ratio of the smaller to larger end moments in the length (L) for segments without transverse loads (positive when the segment is bent in reverse curvature). FLR )

5.2.2.3 Design Torsional Moment Section Capacity The design torsional moment section capacity (qMz ) listed in the 5.2 Table series is determined in accordance with (a) and (b) as noted below. (a) Although AS 4100 makes no provision for the design of members subject to torsion it is nevertheless considered appropriate to provide torsional capacities for hollow sections in the Tables. Hollow sections perform particularly well in torsion and their behaviour under torsional loading is readily analysed by simple procedures. An explanation of torsional effects is provided in Refs. [5.1, 5.2]. The general theory of torsion established by Saint-Venant is based on uniform torsion. The theory assumes that all cross-sections rotate as a body around the centre of rotation.

(b)

When the applied torsional moment is non-uniform, such as when the torsional load is applied midspan between rigid supports or when the free warping of the section is restricted, then the torsional load is shared between uniform and non-uniform torsion or warping. However, in the case of hollow sections, the contribution of non-uniform torsion is negligible and sections can be treated as subject to uniform torsion without any significant loss of precision in analysis. For hollow sections, torsional actions can be considered using the following formulae: Strength Limit State M*z ) qMz qMz = q0.6 fyC where M*z = design torsional moment q = 0.9 (based on shearing loads and Table 3.4 of AS 4100) qMz = design torsional section moment capacity fy = yield stress used in design C = torsional section modulus (see 3.1 Table series) Serviceability Limit State The angle of twist per unit length e (in radians) can be determined from the following formula: M *z e = GJ where G = shear modulus of elasticity, 80 x 103 MPa J = torsional section constant (see 3.1 Table series). The method for determining the constants C and J is detailed in Section 3.2.1.1.

The ratio of maximum to average design shear stress in the web (f vm * / f v*a) for bending about the x-axis is calculated [5.3] using:

Designers must ensure that the design shear force (V *) ) qVv along the beam. RHS and SHS generally have non-uniform shear stress distributions along their webs. Consequently, the design shear capacity of a web (qVv) for most RHS/SHS in the Tables are primarily determined from Clauses 5.11.3 and 5.11.4 of AS 4100 and is calculated as the lesser of: qVv = qVw (Clause 5.11.4 of AS 4100) and

The design web bearing capacity determined in Section 5.2.2.5 of the Tables may be significantly reduced when the section is subject to a large bending moment at the same location. The effect of this interaction of bending and bearing force in RHS and SHS is considered in AS 4100. The bending and bearing interaction is dependent on the ratio of bearing length to the width of bearing (bs /b) and web slenderness (d1/t). Clause 5.13.5 of AS 4100 considers the following interaction to apply to RHS and SHS:

Design Moment Capacities for Members Without Full Lateral Restraint 5.3.1 General

=

Values of design member moment capacity (qMb) are given in Tables 5.3-1 and 5.3-2 for various values of effective length (Le) based on the uniform moment case (_m = 1.0) for RHS bending about the x-axis without full lateral restraint. The design section moment capacity (qMsx – see Section 5.2.2.1) is also listed to allow easy calculation of qMb for other moment distributions, as well as the design shear capacity (qVv – see Section 5.2.2.4) for checking the interaction of shear force and bending. Additionally, the segment length for full lateral restraint (FLR) is also listed in these Tables. CHS and SHS are not included in these tables as they are generally not susceptible to flexural-torsional buckling. For these sections, the design member moment capacity (qMb) always equals the design section moment capacity (qMs) except for the extreme case when the load acts far above the shear centre (Clause 5.6.1.4 of the Commentary to AS 4100 – Ref.[5.1]). Values of qMs (and qVv) are given in Tables 8-1 to 8-2 for CHS and Tables 5.2-3 and 5.2-4 and/or Tables 8-5 and 8-6 for SHS.

5.3.2 Design Member Moment Capacity Designers must ensure that the design bending moment (M*) ) qMb for all beam segments. The tabulated values of design member moment capacity (qMb) are determined in accordance with Clause 5.6.1.4 of AS 4100 as: qMb = q_m_sMs ) qMs where q = 0.9 (Table 3.4 of AS 4100) _m = moment modification factor (Clause 5.6.1.1 of AS 4100) = 1.0 (Assumed for all entries in the 5.3 series tables based on the uniform bending moment case) _s = slenderness reduction modification factor (Clause 5.6.1.1 of AS 4100) ¨ • ¬ ¥2 — £ ¥« « £ (Equation 5.6.1.1(2) of AS 4100) = 0.6 © ³² Ms ´ 3 µ < ² M s ´­ µ ³ Moa ¦« ¤ « –¤ Moa ¦ ˜ ª ® Moa = Mo – the reference buckling moment (Clause 5.6.1.1(a)(iv)(A) of AS 4100)

5.3.3 Beam Effective Length The value of qMb depends on the effective length (Le) of the flexural member. Le is determined by: Le = kt kl kr L (Clause 5.6.3 of AS 4100) where kt = twist restraint factor (Table 5.6.3(1) of AS 4100) kl = load height factor (Table 5.6.3(2) of AS 4100) = lateral rotation restraint factor (Table 5.6.3(3) of AS 4100) kr L = length of segment Ref. [5.4] provides guidance on the restraint conditions on flexural members provided by many common structural steelwork connections. Additionally, Ref. [5.5] considers further guidance on unbraced cantilevers.

5.3.4 Other Loading and Restraint Conditions The design member moment capacities presented in the 5.3 series tables can be used for other loading conditions. For these situations the effective length (Le) corresponding to the actual length and restraint conditions must be assessed and the appropriate value of _m determined in accordance with Clause 5.6.1.1(a) of AS 4100. The design member moment capacity can then be determined as the lesser of: qMsx = qfy Zex and qMb = q_m _s fy Zex where q = 0.9 (Table 3.4 of AS 4100) qMb = _m times the value of qMb (= q_s fy Zex) given in the 5.3 series tables. The 5.3 series tables are based on the most critical moment distribution – i.e. uniform moment over the entire beam segment (_m = 1.0). For other values of _m, designers should use the lesser of qMsx and _m (qMb) where qMb is the value given in the appropriate Table for the same effective length.

The tabulated values of FLR in the 5.3 series tables are based on the conservative value of `m = -1.0. Higher values of FLR may be obtained if transverse loads are present on the beam segment or if the end moments of the beam segment cause other than uniform bending moment – Clause 5.3.2.4 of AS 4100 should be consulted in these situations.

See Section 5.2.4.) It should also be noted that when looking at Table 5.3-2(2) from the “bottom-up” for the entries of qMb > 60.0 kN in the Le = 2.0 m column, the 150 x 100 RHS with 8.0, 9.0 and 10.0 mm thickness in C450PLUS® initially satisfy this inequality. However, the 200 x 100 x 5.0 RHS in C450PLUS® was selected as it satisfies the above inequality and is lower in mass (by at least 20%) and has greater stiffness (by at least 24%) than the above listed 150 x 100 RHS. In terms of design member moment capacity, beam segments 1 and 3 do not have to be checked because they have the same design bending moment (i.e. the maximum segment moment) and end restraints but a shorter effective length when compared with the middle segment. Additionally, the bending moment distribution is less adverse in the end segments (with _m = 1.75 as noted in Table 5.6.1 of AS 4100). As the end segments have a smaller effective length and larger moment modification factor, the design member moment capacity of these segments cannot be less than that of the central (critical) segment.

Thus the required section can be read directly from Table 5.3-2(2) for a uniform design bending moment of 60 kNm on segment 2 with an effective length (Le) of 2.0 m.

This example specifically illustrates the use of the Tables for bending moment and shear design of unrestrained RHS beam sections possibly subject to flexural-torsional buckling (CHS and SHS do not generally experience this instability). However, due to the length, bending moment and restraint conditions, beam segment 2 has full lateral restraint (see Note 4 in Table 5.3-2(2)). The next example considers the above case but without full lateral restraint at the load points (making the RHS subject to flexural-torsional buckling). In all such situations, designers should also undertake checks on bearing (Section 5.2.2.5) and bending-bearing interaction (Section 5.2.5) for the strength limit state and deflections (Sections 5.1 and 5.4) for the serviceability limit state.

FF (i.e. fully restrained at both ends of the segment) 1.0 (Table 5.6.3(1) of AS 4100) 1.4 (Table 5.6.3(2) of AS 4100 with top flange loading within segment) Lateral rotation restraint factor kr = 1.0 (Table 5.6.3(3) of AS 4100) ‘ Effective length Le = kt kl kr L = 1.0 x 1.4 x 1.0 x 4.5 = 6.3 m Moment modification factor _m = 1.07 (Second listing in Table 5.6.1 of AS 4100) To satisfy the strength limit state M* ) qMb = q_m _s Msx ()qMsx) This can be rewritten as M*/_m = 60/1.07 = 56.1 kNm ) q(1.0)_s Msx The right hand side of the last inequality is the value of qMb (based on _m = 1.0) that is found in Table 5.3-2(2). To design this beam from these Tables M*/_m = 56.1 kNm < qMb (listed in Table 5.3-2(2)) Therefore the appropriate section can then be read directly from the table using the adjusted design bending moment of M*/_m. From Table 5.3-2(2), a 200 x 100 x 5.0 RHS – Grade C450L0 (C450PLUS®) has: qMb = 68.6 kNm (for Le = 6.3 m and _m = 1.0 by linear interpolation) > M*/_m (= 56.1 kNm) kt kl

= = =

Alternatively, the listed value of qMb from Table 5.3-2(2) may be multiplied by _m (=1.07) and limited if necessary to qMsx. The resulting value then should be greater than or equal to M*. Hence, in terms of design member moment capacity, the 5.0 mm thick section is adequate – that is the same as in Example 1. The reason for this is due to the effect of the (more favourable) non-uniform moment distribution offsetting the negative effects of increased effective length. (An analysis of the effect of increasing effective length on RHS design member moment capacity sees the level of moment capacity reduction being only gradual). Additionally, from Table 5.3-2(2), for the 200 x 100 x 5.0 RHS – Grade C450L0 (C450PLUS®) section: qVv = 440 kN > V* (Note also 0.6qVv * V* and no shear – bending interaction check is required. See Section 5.2.4.) This example specifically illustrates the use of the Tables for bending moment and shear design of unrestrained RHS beam sections subject to flexural-torsional buckling (CHS and SHS do not generally experience this instability). In such situations, designers should also undertake checks on bearing (Section 5.2.2.5) and bending-bearing interaction (Section 5.2.5) for the strength limit state and deflections (Sections 5.1 and 5.4) for the serviceability limit state.

5.4

Calculation of Beam Deflections

Some methods for calculating the elastic deflection of a beam include: (i) integration of M/EI diagram (ii) moment area (iii) slope deflection (iv) published solutions for particular cases (v) approximate or numerical methods (e.g. finite elements). Table T5.2 gives the more commonly used beam deflection formulae. Due to the large range of loading configurations and support conditions considered for beams in design, a comprehensive set of beam deflection formulae is provided in Ref. [5.6].

Notes: 1. REFER to the Australian Tube Mills PRODUCT AVAILABILITY GUIDE (PAG) for information on the availability of listed sections and associated finishes. The PAG can be found at www.austubemills.com. 2. Australian Tube Mills C450PLUS products satisfy both the strength and elongation requirements of AS/NZS 1163 Grades C350L0 (with the higher elongation requirements) and C450L0 (with the higher strength requirements of fy = 450 MPa and fu = 500 MPa). See Section 2.4.2 for a detailed definition of C450PLUS. 3. W*S = Maximum Serviceability Design Load based on Deflection Limit of SPAN / 250 or First Yield. 4. Red shading indicates serviceability loads governed by yielding. 5. NOTE: Grey shaded listings are to C450L0 which is a non-standard grade - availability is subject to minimum order criteria. The standard grade for the shaded listings is AS/NZS 1163-C350L0. Please refer to earlier tables for design values associated with this as a standard grade. See the ATM PAG for further information on grades and availability.

Notes: 1. REFER to the Australian Tube Mills PRODUCT AVAILABILITY GUIDE (PAG) for information on the availability of listed sections and associated finishes. The PAG can be found at www.austubemills.com. 2. Values of qMb based on _m = 1.0 (uniform moment over entire segment) in this Table. 3. Values to the left of those of the solid line are for segment lengths with full lateral restraint based on the listed FLR and qMb = qMsx. 4. FLR – segment length for Full Lateral Restraint (Clause 5.3.2.4 of AS 4100) with `m = -1.0. 5. For other moment distributions use the appropriate value of _m obtained from Clauses 5.6.1 or 5.6.2 of AS 4100 and use the minimum of _m qMb and qMsx given in this Table.

Notes: 1. REFER to the Australian Tube Mills PRODUCT AVAILABILITY GUIDE (PAG) for information on the availability of listed sections and associated finishes. The PAG can be found at www.austubemills.com. 2. Australian Tube Mills C450PLUS products satisfy both the strength and elongation requirements of AS/NZS 1163 Grades C350L0 (with the higher elongation requirements) and C450L0 (with the higher strength requirements of fy = 450 MPa and fu = 500 MPa). See Section 2.4.2 for a detailed definition of C450PLUS. 3. Values of qMb based on _m = 1.0 (uniform moment over entire segment) in this Table. 4. Values to the left of those of the solid line are for segment lengths with full lateral restraint based on the listed FLR and qMb = qMsx. 5. FLR – segment length for Full Lateral Restraint (Clause 5.3.2.4 of AS 4100) with `m = -1.0. 6. For other moment distributions use the appropriate value of _m obtained from Clauses 5.6.1 or 5.6.2 of AS 4100 and use the minimum of _m qMb and qMsx given in this Table.

General

Values of the design member capacity in compression (qNc) for buckling about each principal axes for a range of effective lengths (Le) are given in Tables 6-1 to 6-6. The design member capacities are determined from Section 6 of AS 4100. All the Tables for CHS, RHS and SHS are supplemented by graphs of qNc versus Le placed consecutively after the tables for each corresponding grade and section type. All loads are assumed to be applied through the centroid of the section. The column capacity is associated with flexural buckling as torsional buckling is not a common buckling mode for hollow sections in axial compression. For RHS only, the Tables in this section have been grouped into two series: the (A) series for the member buckling about the x-axis, and the (B) series for the member buckling about the y-axis. The (A) series tables and graphs for each group of sections are immediately followed by the (B) series of tables and graphs for the same group.

6.2

Design Section Capacity in Axial Compression

The design section capacity in compression (qNs) is obtained from Clause 6.2 of AS 4100 and is given by: qNs = qkf An fy where q = 0.9 (Table 3.4 of AS 4100) kf = form factor (see Section 3.2.2.3) An = net area of the cross section = Ag assuming no penetrations or holes (see 3.1 series Tables in Part 3) fy = yield stress used in design The design section capacity considers the behaviour of the cross-section only (as in a stub column test), and is affected by the element slenderness of each plate element in the cross-section. The form factor (kf) represents the proportion of the section that is effective in axial compression and is determined from considerations of element slenderness as affected by local buckling, using Clause 6.2.3 and 6.2.4 of AS 4100. See discussion in Section 3.2.2.3.

Design Member Capacity in Axial Compression

The design member capacity in axial compression accounts for the effect of overall member buckling for the effective length of the member (amongst other factors) and it is obtained from Clause 6.3 of AS 4100 and given by:  qNc = q_cNs ) qNs where q = 0.9 (Table 3.4 of AS 4100) _c = member slenderness reduction factor The member slenderness reduction factor (_c) depends on the modified member slenderness (hn) and the member section constant (_b).

Part 6 MEMBERS SUBJECT TO AXIAL COMPRESSION Le = effective length of a compression member about the axis of buckling r = radius of gyration about the axis of buckling For routine design the above equations need not be used. Table 6.3.3(3) of AS 4100 may be consulted to obtain the value of (_c) directly once hn and _b are evaluated. Note that the design member capacity equals the design section capacity (i.e. qNc = qNs) when the effective length is zero (i.e. Le = 0). Table T6.1 (which is extracted from Table 6.3.3 of AS 4100) lists values of _b for the sections considered in these Tables.

Effective Length

The values of qNc are based on the effective length (Le) of the member. The effective length depends on the member length (L), the rotational and translational restraints at the ends of the member and is determined from the following formula: Le = ke L The member effective length factor (ke) for use in Clause 6.3.2 of AS 4100 can be determined using Clause 4.6.3 of AS 4100 or by a rational frame buckling analysis (Clause 4.7 of AS 4100). ke is given in Figure 6.1 for members with idealised end restraints (from Figure 4.6.3.2 of AS 4100). For braced or sway members in frames, ke depends on the ratio ( a ) of the compression member stiffness to the end restraint stiffness, calculated at each end of the member. Example 2 of Section 4.3 in Ref [6.1] provides a sample calculation of ke for columns in an unbraced plane frame.

Table T6.2: Possible C450PLUS® RHS options to resist N* = 2400 kN compression.

Example

Design a RHS column, with a length of 5.8 m, in Grade C450L0 (C450PLUS®) steel to resist a design axial force, N* = 2400 kN. Assume that for x-axis buckling both ends are pinned (rotation free, translation fixed), while for y-axis buckling one end is rotation free, translation fixed (pinned) and the other end is rotationally and translationally fixed. Design Data: N* = 2400 kN Solution: (i) Determine effective lengths For x-axis buckling ke = 1.0 (Figure 6.1) ‘ Lex = ke L = 1.0 x 5.8 = 5.8 m 5 6.0 m For y-axis buckling ke = 0.85 (Figure 6.1) ‘ Ley = ke L = 0.85 x 5.8 = 4.93 m 5 5.0 m (ii) Select a member When looking up Tables 6-4(1)(A) and 6-4(1)(B) from bottom to top there are various sections for which N* < qNc. As such there is the possibility that the first sections being sighted are uneconomical. In order to select a more optimal section it may be prudent to summarise a few of the initial listings for qNcx and qNcy based on their respective effective lengths. This is summarised in Table T6.2 for the example being considered.

General

Tables 7-1 to 7-6 give values of design section capacity in axial tension. Section 7 of AS 4100 has been used to determine these values. The Tables list the design section capacity in tension for Australian Tube Mills structural steel hollow sections. It further assumes that there are no eccentricity, shear lag or stress concentration effects such that there is a uniform stress distribution along the cross-section (e.g. as in full perimeter welded connections to uniformly stiff supports - see Clause C7.3.1 of Ref. [7.1]).

7.2

Design Section Capacity in Axial Tension

The design section capacity in axial tension (qNt) listed in the Tables has been determined from Clause 7.2 of AS 4100 and is taken as the lesser of: qNt = qAg fy (yielding of the gross section) qNt = q(0.85)kt An fu (fracture of the net section) where q = 0.9 (Table 3.4 of AS 4100) fy = yield stress used in design fu = ultimate tensile strength used in design Ag = gross area of the cross-section An = net area of the cross-section = Ag (e.g. for full perimeter welded connections to uniformly stiff supports) kt = 1.0 (Clause 7.3.1 of AS 4100) The lesser value of qNt(1) = qA g fy and qN t(2) = q(0.85)Ag fu is highlighted in bold type in the Tables.

Example

1.

A tension member with a full perimeter welded connection to a uniformly stiff support is subjected to an axial tension force of 150 kN. Design a suitable RHS tension member. Design Data: N* = 150 kN kt = 1.0 (for a full perimeter welded connection) Solution: Select a suitable RHS member from Tables 7-4(2). The alternatives are: 76 x 38 x 4.0 RHS – Grade C450L0 (C450PLUS) (6.23 kg/m) qNt = 303 kN > N* 100 x 50 x 3.0 RHS – Grade C450L0 (C450PLUS) (6.60 kg/m) qNt = 322 kN > N* Both these options are suitable for the design as their mass is somewhat similar. The final choice of section may be influenced by other constraints (geometric, availability etc.).

Note: For AS/NZS 1163 Grade C250L0 and C350L0 CHS, qNt = qAg fy is always less than qN t = q(0.85)Ag fu though for RHS/SHS to AS/NZS 1163 Grade C450L0 qNt = q(0.85)Ag fu is the lesser value of qNt. For sections reduced by penetrations or holes, the value of qNt can be determined from the Tables as the lesser value of: qNt = qA g fy and qNt = q(0.85)k t A g f u (A n /A g ) where An = net area of the cross-section kt = tension correction factor (Clause 7.3.1 of AS 4100) Values of Ag are tabulated in Tables 7-1 to 7- 6. Note that all the values in Tables 7-1 to 7-6 assume kt = 1.0. Australian Tube Mills A.B.N. 21 123 666 679.

Tables 8-1 to 8-6 Design Section Capacities

8-9 Tables 8-1 to 8-6 provide the information required to design members for combined actions. All relevant design section capacities in bending, compression, tension and shear are given as well as reduced design section moment capacities. These tables also provide reference to the appropriate tables in Sections 5, 6 and 7 to determine design member capacities in bending, axial compression and axial tension.

See Section 2.1 for the specific Material Standard (AS/NZS 1163) referred to by the section type and steel grade in these Tables.

Design for Combined Actions

Sections 8.3 and 8.4 explain the relevant equations from AS 4100 for combined bending and axial compression and combined bending and axial tension respectively. Each of these sections consider uniaxial bending about the major principal x-axis, uniaxial bending about the minor principal y-axis and biaxial bending. Section 8.5 gives the interaction formulae for biaxial bending without axial forces. In every case both the section capacity and the member capacity must be checked.

For all cases of combined bending and axial force the designer should first ensure that the appropriate design axial capacity (compression or tension) is greater than the design axial force (i.e. qN * N* ) – see part 6 or 7 as appropriate.
