摘要

基于摩擦摆(FPS)及其隔震剪切型结构非线性振动微分方程,通过数值模拟分析了摩擦摆隔震系统对结构最大地震响应的影响。结果表明,经过合理设计的摩擦摆系统能够显著改善上部结构的地震反应,并有效控制底部钢筋混凝土框架的水平侧移,从而具有良好的隔震性能。
Based on the non-linear differential equations of FPS-isolated system and its shear-type structure,by using numerical simulation the most remarkable seismic response effect of FPS-isolate system is analyzed.The results show that the reasonable designed friction pendulum system can obviously improve the seismic response of superstructure and can effectively control lateral displacement of FPS-isolated building with a RC frame structure as its bottom story.And thereby FPS-isolated system has good capacity of isolating horizontal earthquake actions.
