Abstract
In this paper, we propose a response estimation method for seismic isolated structure with roller bearings and/or sliding bearings. The system of sliding bearing can be replaced with that of roller bearings. <br>Estimation with equivalent linear system is not suitable for these systems. This method is based on the theory of energy balance. The process is as follows. 1) Estimate velocity of system by spectrum intensity. 2) Calculate absorption energy. 3) Estimate displacement of system by balance of absorption energy and momentum input energy. The estimated values are well coincided with results of time history response analysis.
