摘要

摩擦摆隔震支座由于其良好的隔震性能,在国外被大量应用于各类建筑结构中,而国内对于摩擦摆的研究和应用还相对较少。本文应用美国纽约州立大学Buffalo分校开发的3D-BASIS-ME程序,结合同济大学摩擦摆隔震支座模拟地震振动台试验结果,对摩擦摆隔震系统在地震作用下的数值模拟问题进行了探讨,详细讨论论摩擦摆隔震系统参数的取值方法,并完成了摩擦摆隔震系统的建模分析,数值仿真分析结果与试验结果吻合良好,表明隔震系统参数选取合理,3D-BASIS-ME软件能很好地模拟摩擦摆隔震系统在地震作用下的力学行为。
Because of its good isolation properties,the friction pendulum bearings have been widely applied in various building structures overseas; however,the researches and applications of FPS in China are still in the initial stage. This paper is aiming to the numerical simulation of FPS under earthquake excitation by using 3D-BAIS-ME developed by the State University of New York Buffalo and shake table test results of friction pendulum bearings at Tongji University,the parameters of FPS are discussed and the numerical results show that 3D-BAIS-ME is effective for numerical simulation and analysis of FPS under earthquake excitation.
