Which of the following structural elements is primarily responsible for resisting lateral seismic loads in a wooden frame house in Japan?
A. Floor joists
B. Roof rafters
C. Sheathing boards (plywood or OSB)
D. Window frames
E. Door frames
Answer: C
Explanation: In Japanese wooden frame houses, sheathing boards (typically plywood or OSB) attached to the wall frames form shear walls, which are the primary elements resisting lateral seismic loads. They distribute seismic forces and prevent the building from racking, a key aspect of wooden building seismic design.
