【摘要】 橡胶垫基础隔震技术作为一种有效的减震控制之一,在实际工程中得到了广泛的运用。对基础隔震结构非比例阻尼体系动力响应的时域解答进行了较详细推导,并用Matlab软件编制了相应的求解程序,最后以一栋5层剪切型结构为例进行仿真分析。分析结果表明,橡胶垫基础隔震能够显著降低结构的层间位移响应和加速度响应,提高结构的整体抗震性能。更多还原

【Abstract】 The rubber bearing base isolation as one of the effective control of damping systems has been widely used in the actual projects.The time-domain solution of the non-proportional damping system of base isolation structure is derived,and the correponding softwate program with Matlab software was established,finally,the simulation analysis with a 5-story shear-type structure is conducted.The results show that the rubber bearing can singificantly reduce the story drift response and acceleration response and improve the whole seismic performance of the structure.更多还原
