本文推导和建立了单面ＦＰＳ隔震系统的多层剪切型结构在水平地震作用下的状态方程及状态转换条件，在其基础上，计算分析了该结构的性态和地震响应规律。结果表明，ＦＰＳ具有良好的稳定性、限位复位功能和显著的隔震效果。
This paper deduces and establishes the state equations and state transition conditions of the multi-layer shear structure of a single-sided FPS seismic isolation system under horizontal earthquakes. Based on this, the behavior and seismic response of the structure are calculated and analyzed. The results show that FPS has good stability, limit reset function and significant isolation effect.
