Study on FPS-isolation vibration with variable sliding friction coefficient

基于摩擦摆隔震结构的振动微分方程 ,将摩擦摆系统的滑动摩擦系数作为速度的函数 ,通过数值模拟研究了摩擦摆系统参数对结构最大地震响应的影响。结果表明 ,摩擦摆具有良好的隔震性能。

Based on the vibration equations of FPS-isolated structures, considering the sliding friction coefficient of FPS bearings as the function of the sliding velocity of FPS, the influence of the parameters of FPS on the maximum seismic responses of a base-isolated structure is studied by numerical simulations. The results indicate that FPS bearings have good capacity of isolating horizontal earthquake actions.
