Code for the Design of Concrete Structures for Buildings
|Publication Date:||1 January 1977|
This Standard applies to the design of building structures of reinforced (prestressed or non-prestressed) concrete.
For special structures such a arches, tanks, reservoirs, grain elevators, blast-resistant structures and chimneys, and for plain concrete, the provisions of this Standard shall govern so far as they are applicable.
The National Building Code of Canada provides that the constituent elements of certain building structures are required to have a specified fire resistance rating. The rules for establishing fire resistance ratings are given in the code, which makes reference to Supplement No.2, of the National Building Code of Canada, Fire Performance Ratings. Supplement No.2 assigns fire resistance ratings to certain concrete walls, floors, roofs, columns and bearns designed in accordance with this Standard. The fire resistance rating that Supplement No.2 may assign to a specific concrete assembly depends upon the type of concrete from which the assembly is constructed, the dimensions of the assembly, the type of reinforcement used, its concrete cover and other factors. Users of this Standard shall refer to the provisions of the National Building Code of Canada, Part 3 for guidance as to the fire resistance rating, if any, which may be assigned to building structures designed in accordance with this Standard.
