Base Shear Coefficient for Wooden Houses on Recent Observed Earthquake Motions in Japan

Abstract

There are many observed strong motions over the assumption of Japanese codes. The proper base shear coefficient on these strong motions is required for high specification houses. In this paper, the relation between SA-SD curves of these strong motions and the response of time history analysis is discussed. As a result, it is hard to resist recently strong motions for the house whose base shear coefficient is 0.6. The requires that the base shear coefficient required by the strongest motion is over 1.0.
