Adopted in the BC Building Code 2024 are new Part 9 bracing requirements for wood frame construction, coming into effect on March 10, 2025. The redesign of Section 9.23. is substantially changed to accommodate modern housing design and higher seismicity, mainly Subsection 9.23.13. Bracing to Resist Lateral Loads Due to Wind and Earthquake. The increased seismicity warranted a redesign of the methods for resisting lateral loads and new solutions so that designers can continue to design within Part 9. These changes will apply to all Part 9 housing in BC, including low seismic and wind locations.

Course overview:

• Background of the Part 9 changes to lateral load resistance (What, When, Why)
• Key terms (braced wall bands, braced wall panels)
• Compliance paths, including limitations of Part 9 design
• Basic calculation of Part 9 compliance paths
• Braced wall panel options (materials, dimensions, fasteners)
• Allowable exceptions
