When an isolation device is used, big relative displacement arises between the device and the ground. The purpose of this research is to make relative displacement smaller by friction. Then, the analysis model that is considered friction was created, and simulation analysis was performed with the actual seismic wave. As a result, as friction becomes larger displacement becomes smaller. However, it is turned out that response acceleration becomes larger. Moreover, an experimental model is created, carried out and compared with a result of an analysis. Furthermore, it is thought that the optimal frictional force which makes both response acceleration and displacement small exists. This is considered to change with seismic waves. Then, the decreases in response acceleration and response displacement are investigated through the. relation between input acceleration and the optimal frictional force, using simulation analysis.
