【Abstract】 The analysis on energy response of base-isolated structures with friction pendulum system is carried out,the effect of the bearing friction coefficient and the seismic intensity on the energy response is studied.As the friction coefficient of the FPS increasing,the total input energy and the potential energy dissipation ratio of the superstructure will increase,and the energy dissipation ratio of base-isolation system will decrease.As the seismic intensity increasing,the total input energy and the energy dissipation ratio of base-isolation system will increase,the potential energy dissipation ratio of the superstructure will decrease.更多还原
