    通过模型振动台试验研究采用复摩擦隔震支座（MFPB）的楼面隔震性能。试验结果表明，隔震层上部荷载变化对MFPB隔震效果没有影响；MFPB与黏滞阻尼器的协同工作能够控制隔震楼面的位移；竖向地震动对MFPB的水平隔震效果无明显影响；用SAP2000中的摩擦连接单元模拟MFPB隔震效果的精度是满足工程需求的。

    The isolation efficiency of multiple friction pendulum bearings (MFPB)was checked with shaking table tests.The results showed that changes of load on the isolation layer have no influence on the isolation efficiency of MFPB;combining MFPB with viscous dampers can control displacements of an isolated structure;the vertical seismic input has no significant impact on the horizontal isolation effect of MFPB;the simulation accuracy for isolation effect of MFPB with friction-connection elements in SAP2000 can meet the requirement of engineering applications.
