Preface
This new edition of CSA Standard A23. 3, Code For the Design of Plain or Reinforced Concrete, supersedes previous editions published in 1959 and 1966.
It differs mainly from the previous edition in that it has been editorially rearranged to permit its inclusion, en toto, in the 1970 National Building Code, Design Supplement. Although no major changes have been introduced numerous changes of a minor nature have been made.
Scope
1.1 Scope
This Standard applies to the design of building structures of plain or reinforced concrete.
1. 2 Special Structures
