We have ever applied PFT-ELS (Equivalent linear system using the restoring force model of power function type) method to analyze the nonlinear vibration characteristic of seismic isolation laminated rubber. However, the restoring force characteristics cannot express shapes like experimental values in the PFT-ELS method. Therefore, in this research, we apply PFT-HYS (Hysteresis system using the restoring force model of power function type) which can accurately express the restoring force characteristics more than the PFT-ELS for the nonlinear vibration analysis of the seismic isolation laminated rubber. Then, the analysis results of PFT-HYS method is compared with the PFT-ELS method.
