1. Scope and Application

1.1

This Standard applies to the design, based on limit states, of structural members cold formed to shape from carbon or low- alloy steel sheet, strip, or plate up to 25 mm thick and intended for load-carrying purposes in buildings. For application other than in buildings, supplementary specifications shall be used where necessary to account for differences in structural loads and effects, environment, and other service conditions.

1.2

Where a structure consists of cold formed steel structural members, provision shall be made to ensure adequate stability of the structure as a whole, and adequate lateral, torsional, and local stability of all structural parts so as to provide resistance to widespread collapse due to local failure. Supplementary provisions may be required for structures where accidental loads such as vehicle impact or explosion may occur. Where members designed in accordance with this Standard are intended for use in structures where other recognized standards apply, this Standard shall supplement such standards as applicable.

1.3

The resistance factors adopted in this Standard are correlated with the loads and load factors for buildings as specified in the National Building Code of Canada and Clause 4 of this Standard. For other cases, load factors shall be established such that, in conjunction with the resistance factors used in this Standard, the required level of reliability is maintained.

1.4

Where this Standard provides design expressions or dimensional limitations that are not applicable to a specific situation, a rational design may be used if based on appropriate theory, test, analysis, and engineering judgement.
