べき関数型等価線形系解析手法を用いた免震積層ゴムの非線形振動解析

抄録

In this paper, we describe an original method (PFT-RFM: Restoring Force Model of Power Function Type) for analyzing nonlinear vibrational properties of the seismic isolation laminated rubber. We also describe an original method (PFT-ELS: Equivalent Linear System using the restoring force model of Power Function Type) for analyzing response of the high-rise building structure with the seismic isolation laminated rubber for many earthquakes. We were able to verify the appropriateness of those methods by directly comparing the analysis result of those methods with the analysis result of the modified bilinear model. As a result, usability of PFT-RFM and PFT-ELS could be confirmed.
