【Abstract】 The performance of base-isolated structure with top PTMD for suppressing the seismic response is studied.The numerical model of the hybrid control system is established.And the bilinear hysteretic model is applied to simulate the hysteretic characteristics of the rubber bearing isolation cushion.The Simulink is adopted to solve the dynamic differential equations.Based on the seismic dynamic time history response of some specific structures,simulated analysis demonstrates that the effectiveness of the hybrid control system is superior to that of the single PTMD control system.更多还原
