Preface
This is the first edition of CSA Standard CANS-S16.1-M. Steel Structures for Buildings - Limit States Design.
This Standard along with CSA Standard S16.1-1974, takes its place beside CSA Standard S16-1969, Steel Structures for Buildings, which is based on working stress design and supersedes previous editions of 1965, 1961, 1954, 1940, 1930 and 1924. CSA Standard S16-1969 will continue to provide engineers with a working stress design standard for some time.
CAN3-S16.1-M is the first such standard for steel structures if Canada prepared in SI units (Le Système Internationale d'unités). In limit states design, the designer compares the effect of factored loads to the minimum likely developable resistance; no longer does he compute working stresses to compare with allowable values. Limit states define the various types of collapse and unserviceability that are to be avoided and the object of design is to keep the probability of a limit state being reached below a certain value previously established. This is achieved by applying load factors to the specified loads and performance factors to the specified resistances. These factors replace the single factor of safety used in other design standards. The factors used in this Standard have been determined by calibration with the existing CSA Standard S16-1969. By the use of different factors, for example, for different loads, a more uniform level of safety is obtained.
A considerable number of technical changes, reflecting the latest research developments, have also been incorporated in this Standard. These are based on an increased understanding of the behavior of steel structures, members and elements, and of steel as a structural material.
As in CSA Standard S16-1969, the clauses relating to fabrication and erection show that design cannot be considered by itself but that it is part of the design and construction sequence.
This Standard sets out minimum requirements for steel structures as outlined in the Scope and, it is expected, will only be used by engineers competent in this field.
CSA Standard S16.1-1974, on which this Standard is based, has been adopted by the Associate Committee on the National Building Code as the reference standard, along with the seventh edition of S16-1969, for Section 4.6 of the National Building Code for 1977. It is expected that CAN3-S16.1-M will be adopted in the next revision of the National Building Code.
Scope
1.1
This Standard provides rules and requirements for the design, fabrication and erection of steel structures for buildings where the design is based on limit states. The term steel structures relates to structural members and frames which consist primarily of structural steel components, including the detail parts, welds, bolts, or other fasteners required in fabrication and
erection.
1.2
This Standard does not cover the design, fabrication, and erection of steel structures other than for buildings except as permitted by the authority having jurisdiction.
1.3
Where reference is made to other publications, such reference shall be considered to refer to the latest edition or any revision thereto approved by the organization issuing that publication.
1.4
When designing structures under this Standard, no use shall be made of CSA Standard S16-1969, Steel Structures for Buildings.
