| 摘 要： | 以一个摩擦摆隔震五层剪切型结构为例,采用有限元分析程序,计算分析了隔震与非隔震上部结构振动状态和能量响应规律.结果表明,滑移隔震对于上部结构振动响应的隔震效果受能量方面的机理控制.由于滑动摩擦层耗散了绝大部分的地震输入能量,采用摩擦摆基底隔震措施以有效降低上部结构的最大加速度和层间位移反应.

| Abstract: | It has been analyzed the vibration status and energy response of a five-floor shear structure with and without FPS isolator using the finite element program.The results show that the energy response has an important effect on the slipping isolator efficiency of the vibration characteristics of the structure.As the slipping isolator consumed most of the input energy of earthquake,the structure with the base FPS isolator has been reduced the peak value of acceleration and displacement between floors of the structure effectively. |
