S413 specifies the minimum design, construction, and maintenance requirements necessary for the structural durability of new parking structures, storage garages, and parts of buildings subject to vehicular traffic or used for parking. The requirements of this Standard are applicable to all parking structures susceptible to corrosion, whether the corrosion is caused by atmospheric conditions or de-icing chemicals.
The provisions of this Standard are intended to address both ultimate and serviceability limit states, and
more specifically, to
(a) protect against the deterioration of concrete and steel elements caused by de-icing chemicals alone
or by de-icing chemicals in combination with the effects of freeze-thaw cycling;
(b) protect against damage to vehicles caused by leakage through floors; and
(c) control the flow of water and avoid ponding.
The structural design methods, loadings, and limit states referenced and specified in this Standard are
those set forth in the National Building Code of Canada.
This Standard differs from the previous edition as follows:
(a) Table 1 has been revised to allow additional combinations of protection systems and concrete cover.
(b) A specific design slope for floors adjacent to walls, columns, and joints has been added.
(c) The requirements for painting of steel structures have been revised.
This Standard has been adopted by the Canadian Commission on Building and Fire Codes as the
reference standard for parking structures in Section 4 of the National Building Code of Canada.
The commentary in Annex H provides explanatory material, as well as useful supplementary information.
Preface This is the third edition of CSA S413, Parking structures. It supersedes the previous editions published in 1994 and 1987.
1. Scope1.1 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.
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: Repair of concrete structures is covered in CSA S448.1.
1.4 Reference standards In the event of conflict between this Standard and the reference standards, this Standard takes precedence.
1.5 Terminology In CSA Standards, 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; and can is used to express possibility or capability. 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.
