结构隔震体系地震反应分析
Analysis on Seismic Response of BaseIsolation Structures
【摘要】 运用整体有限元法建立了隔震体系在时域内求解的运动方程,并在此基础上考虑了隔震体系的恢复力特性,编制了地震反应计算程序.计算了输入E1-Centro(N-S)地震波时体系的动力反应.计算结果表明:隔震体系上部结构的加速度反应大大降低
【Abstract】 The motion equations for the dynamic analysis of the base isolation structures in the time domain is established by using the finite scheme.Based on it the finite element program is drawn up taking into consideration of the hysteretic behavior of the isolation system.The dynamic response of the base isolation structures under ELCentro (NS.1940) ground motion excitation is evaluated.The computed results show that the acceleration response of the superstructure decreases.
