| 摘 要： | FPS摩擦摆是一种新兴的隔震装置,具有良好的限位复位功能。本文将FPS摩擦摆置于基础与上部建筑之间的隔震层,成功地完成了5层框架的FPS摩擦摆隔震装置的模拟地震振动台试验,这也是我国进行的第一个运用FPS摩擦摆隔震装置的模拟地震振动台试验。试验结果分析表明:FPS摩擦摆隔震装置能够有效地延长上部建筑物的自振周期,减少地震作用对上部结构的影响,隔震效果明显,不失为一种有效的隔震装置。

| Abstract: | Friction pendulum system is a new type of isolated bearing that has favorite functions of restriction and restoration.In this paper,the FPS bearings have been installed into the isolated layers between foundations and buildings and a shaking table test of a five-floor steel-frame model has been completed successfully in Beijing Polytechnic University.The experiment's results indicate that FPS is an effective isolated device which can length the natural period and reduce the earthquake effect on upper structure. |
