CSA S413:21

1 Scope 1.1 General This Standard specifies special requirements for the durability aspects of the design and construction of new parking structures and parts of buildings subject to vehicular traffic. This includes pedestrian traffic areas adjoining to or contained within parking structures. These include areas such as stairs, and pedestrian bridges from parking structures. The application of this Standard includes structures which are designed for the storage and/or repair of vehicles whether those structures are stand alone, above ground or below ground, part of or connected to the structure of a larger structure/development. Note: This includes commercial, residential, industrial or institutional, and all other building types. 1.2 Structure types New parking structures constructed of structural steel, reinforced concrete (including prestressed concrete), or a combination of these materials fall within the scope of this Standard. 1.3 Repair of existing parking structures This Standard does not cover the repair of existing parking structures, and the provisions of this Standard are not necessarily appropriate for the repair and protection of existing structures. Note: See CSA S448.1 for information on the repair of concrete structures. 1.4 Reference standards In the event of conflict between this Standard and the reference standards, this Standard takes precedence. 1.5 Terminology In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
