摘　　要：对摩擦摆基础隔震结构进行了能量反应分析,研究了支座摩擦系数和地震烈度对结构能量反应的影响,表明随着支座摩擦系数的增大,结构的总输入能量增大,隔震层耗能比减小,上部结构的变形耗能比增大;随着地震烈度的提高,结构的总输入能量显著增大,隔震层耗能比增大,上部结构变形耗能比减小.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 suoerstructure will decrease.
