Which documents underpin seismic design concepts in western Canadian practice?

• A. International Building Code and local amendments
• B. NBCC and CSA standards
• C. AISC design manuals
• D. Eurocode

Answer: (B)

Seismic design in western Canada follows Canadian standards, not American or European codes. The main framework is the National Building Code of Canada, which provides the earthquake loading rules, performance objectives, and the overall structural design procedure used across the country. Complementing that, CSA standards give the detailed rules for designing with specific materials (like concrete, steel, and wood) and for the detailing necessary to achieve seismic resistance. Provinces, including Alberta, adopt the NBCC and apply their own amendments, so these documents form the backbone of seismic design practice in the region. The other options are regional or material-specific references from the U.S. or Europe and aren’t the standard foundation for western Canadian seismic design.
