Issues & Performance

BC Gov: Code Bulletin On Seismic Structural Design For Part 9 Wood-Frame Buildings
BC Ministry of Housing bulletin clarifies the application of Section 9.4. Structural Requirements in the 2006 BC Building Code, specifically for seismic structural design of Part 9 wood-frame buildings that fall within the scope of Sentence These Part 9 wood-frame buildings have no specified earthquake or wind loads and are not required by the BC Building Code to be designed for lateral loads. (PDF)
