For wood structural panel shear walls in California high seismic zones, what is the maximum aspect ratio (height to width) allowed for a shear wall segment when using 15/32-inch OSB with 8d common nails at 4 inches on center at panel edges?
Correct Answer
A) 3.5:1
CBC Table 2306.3.1 limits wood structural panel shear wall segments to a maximum aspect ratio of 3.5:1 when using the specified nailing schedule. This limitation ensures adequate stiffness and prevents excessive deflection during seismic loading, which is critical for California's seismic design requirements.
Why This Is the Correct Answer
CBC Table 2306.3.1 limits wood structural panel shear wall segments to a maximum aspect ratio of 3.5:1 when using the specified nailing schedule. This limitation ensures adequate stiffness and prevents excessive deflection during seismic loading, which is critical for California's seismic design requirements.
