Abstract

This paper studies the effect of spatially random ground motions on the seismic response of a one-story multi-span wooden building considering the stiffness of the horizontal diaphragms. The deformation angles at columns and horizontal diaphragms are examined using time history response analyses with simulated input motions. It is shown that stiffness increase of the horizontal diaphragms and dimensions increase of the building make responses large to damage, and that large responses at the horizontal diaphragms are much more serious than at columns.
