In California seismic design category D2, what is the maximum height-to-width ratio allowed for wood structural panel shear walls without special detailing?
Correct Answer
C) 3.5:1
CBC Section 2305.3.4 limits wood structural panel shear walls to a maximum height-to-width ratio of 3.5:1 in seismic design category D2. Exceeding this ratio requires special detailing and analysis to ensure adequate stiffness and prevent excessive deflection during seismic loading, which is critical in California's high seismic zones.
