Description

<p>In this paper, time history response analysis considering the multi-cyclic characteristics of the isolation devices by the simplified method is performed using the long period ground motion for each target area due to Nankai Trough Earthquake. Moreover, time history response analysis of changing the arrangement of the isolation devices is performed in order to investigate the differences in the response characteristics of the base-isolated buildings, and attention points for aseismic design are indicated. In addition, the behavior of the collision to retaining wall is confirmed in the case where large deformation occurs in an isolation story.</p>
