Preface
Please note: this does not include the CISC HandbookThis is a consolidated reprint, incorporating Update No. 1 - June 2003, Update No. 2 - December 2003 and Supplement No. 1 - January 2005
Consists of the CSA standard CAN/CSA-S16-01, Limit States Design of Steel Structures along with S16S1-05, Supplement #1 to CAN/CSA-S16-01, Limit States Design of Steel Structures and replacement pages issued June 2003 and December 2003 as Update #1 and Update #2 to CAN/CSA-S16-01, Limit States Design of Steel Structures incorporated into the original 2001 standard.
Update #1 was published as notification that this is now a National Standard of Canada
Intended Use
This Standard is appropriate for the design of a broad range of structures. It sets out minimum requirements and is expected to be used only by engineers competent in the design of steel structures.
Although the basic limit states format, has proven itself in use and remains unaltered, a considerable number of technical changes reflecting the latest research developments and changes in practice have been incorporated. These changes are based on an increased understanding of the behaviour of structural materials and members, and thus of the overall behaviour of structures, as well as on major advances in methods of structural analysis and on improvements in fabrication and erection. New appendices have been added on crane-supporting structures, arbitration procedure for pretensioning connections, and ductile moment-resisting connections.
The clauses related to fabrication and erection, which are revised considerably, serve to show that design is inextricably a part of the design-fabrication-erection sequence and cannot be considered in isolation. For matters concerning standard practice pertinent to the fabrication and erection of structural steel not covered in this Standard, see Appendix A.
This Standard is compatible with the companion action approach for load combinations introduced in the National Building Code of Canada in 2003.
Scope
1.1 General This Standard provides rules and requirements for the design, fabrication, and erection of steel structures. The design is based on limit states. The term steel structures refers to structural members and frames that consist primarily of structural steel components, including the detail parts, welds, bolts, or other fasteners required in fabrication and erection. This Standard also applies to structural steel components in structures framed in other materials.
1.2 Requirements Requirements for steel structures such as bridges, antenna towers, offshore structures, and cold-formed steel structural members are given in other CSA Standards.
1.3 Application This Standard applies unconditionally to steel structures, except that supplementary rules or requirements may be necessary for (a) unusual types of construction; (b) mixed systems of construction; (c) steel structures that (i) have great height or spans; (ii) are required to be movable or be readily dismantled; (iii) are exposed to severe environmental conditions or possible severe loads such as those resulting from vehicle impact or chemical explosion; (iv) are required to satisfy aesthetic, architectural, or other requirements of a non-structural nature; (v) employ materials or products not listed in Clause 5; or (vi) have other special features that could affect the design, fabrication, or erection; (d) tanks, stacks, other platework structures, poles, and piling; and (e) crane-supporting structures.
1.4 Other Standards The use of other standards for the design of members or parts of steel structures is neither warranted nor acceptable except where specifically directed in this Standard. The formulae provided in this Standard may be supplemented by a rational design based on theory, analysis, and engineering practice acceptable to the regulatory authority, provided that nominal margins (or factors) of safety at least equal to those intended in the provisions of this Standard are maintained.
