User’s Guide – NBC 2015 Structural Commentaries (Part 4 of Division B)
|Publication Date:||1 January 2015|
The Commentaries presented herein serve to provide designers with detailed design information that will assist them in the application of Part 4 of Division B of the National Building Code of Canada (NBC) 2015. They contain background information and suggested approaches to certain design issues; their provisions are not mandatory requirements of the NBC.
The information set forth in these Commentaries does not cover all conditions and types of structures that occur in practice. For unusual types of structures, specialized information, such as theoretical studies, model tests or wind tunnel experiments, may be required to provide adequate design values. It should also be noted that new information can become available at any time. As such, designers are encouraged to obtain the latest and most appropriate design information available.
The Commentaries were updated by the 2010-2015 and 2015-2020 Standing Committees on Structural Design and Earthquake Design of the Canadian Commission on Building and Fire Codes to reflect technical changes made to Part 4 of the NBC 2015.
