| 摘 要： | 本文以一座7层框架结构作为研究对象,运用有限元分析软件SAP2000,对摩擦摆基础隔震结构进行地震反应分析,输入地震波EI-Centro波,通过调整摩擦摆支座的摩擦系数,分析在不同的摩擦系数下结构的周期、基底位移、楼层加速度的影响变化,表明随着支座摩擦系数的增大,结构自振周期逐渐变小,楼层的滑动位移反应也呈减小的趋势,但楼层加速度反应会逐渐变大,为滑移隔震技术应用到实际工程提供了参考依据。

| Abstract: | In this paper, the seismic responses of the sev-en-storey base-isolated structure with friction pendulum were analyzed using the finite element analysis software SAP2000. EI-Centro wave were input as seismic waves. By adjusting the friction coefficient of friction pendulum bearings, the influence of the period of the structure changes, the base displacement changes and the floor acceleration changes were analyzed under the different friction coefficient of the structure. Shows the with the bearing friction coefficient increases, the period of the struc-ture gradually becomes smaller, the sliding displacement of the floor also showed a decreasing trend, while the floor acceleration will gradually become larger. For earthquake isolation technolo-gy applied to practical engineering provides a reference basis. |
