Introduction and Purpose
The Commentaries presented in this guide provide designers with detailed design information intended to assist in the application of Part 4 of Division B of the National Building Code of Canada (NBC) 2015. These commentaries contain background information and suggested approaches to certain design issues. It is important to note that 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 encountered 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. Designers are encouraged to obtain the latest and most appropriate design information available, as new information can become available at any time.
