Abstract

This study is to assess the impact of damping models of superstructure on the seismic isolation effect of High-Rise buildings. First the setting method of damping matrix on seismic isolation structure is shown, and then based on it, relationship between earthquake responses and structural properties; natural period of superstructure, initial stiffness of Bi-linear damper and natural frequency dependence of damping ratio is analyzed by focusing on deformation and absorption energy of isolation story, shear coefficient and acceleration response.
