National Building Code of Canada 2010 – Emergency Changes

Two emergency changes that apply to the National Building Code of Canada 2010 (NBC) have been approved for immediate release by the Canadian Commission on Building and Fire Codes for reasons of safety. These changes affect Sentence 5.2.2.1.(2) of Division B and its Appendix Note. They are necessary as the original wording can be misinterpreted to mean that structural components of buildings associated with the building envelope do not need to be designed for earthquake unless the building is classified as a post-disaster building. The sentence in question has been reworded to make it clear that the earthquake design of all structural components must conform to Article 4.1.8.18.

Replacement pages for these changes can be downloaded and printed from the Internet at http://www.nrc-cnrc.gc.ca/eng/ibp/irc/codes/revisions.html.

Clients who purchased an on-line concurrent user subscription to the NBC can view the updated code by visiting http://irc-cgonline2.irc.nrc.ca/IRC_CGONLINEUI/index.html and clicking on the link to the updated document.
