What is the maximum spacing allowed for holdown anchors at the end of wood structural panel shear walls in California high seismic areas?
Correct Answer
B) 6 inches on center maximum
Per CBC Section 2305.3.8 and Table 2306.4.1, holdown anchor bolts at shear wall ends must be spaced at maximum 6 inches on center in high seismic areas. This closer spacing ensures adequate load transfer from the holdown device to the foundation, which is critical for the lateral force resisting system performance during seismic events.
Why This Is the Correct Answer
Per CBC Section 2305.3.8 and Table 2306.4.1, holdown anchor bolts at shear wall ends must be spaced at maximum 6 inches on center in high seismic areas. This closer spacing ensures adequate load transfer from the holdown device to the foundation, which is critical for the lateral force resisting system performance during seismic events.
