摘　　要：本文推导了FPS(Friction Pendu lum System)隔震结构在平移-扭转耦联情况下的动力反应方程,计算了单层框架结构的地震响应。分析了上部结构偏心对地震反应的影响,对比了结构在不同偏心时的反应并分析了FPS隔震装置的摩擦系数、滑道半径对其抗震性能的影响。In the paper, the vibrational equation of FPS-based structures with translation-torsion coupling is derived and the seismic responses of one-story structure are calculated. The influences of eccentricity of upper-structure on seismic responses are analyzed. By comparing the responses of structures with different eccentricities, an analysis of influences of sliding friction coefficient and slideway radius of FPS isolator on the seismic performance of structure is presented.
