【摘要】 以高层建筑基础隔震设计的基本要求和难点为基础,利用有限元分析软件SAP2000对某高层框架-剪力墙结构在不同地震波作用下进行动力时程分析,得出上部结构相同的采用基础隔震和不隔震建筑的层间位移和最大楼层剪力,并将两者进行比较。分析表明,框架-剪力墙基础隔震结构采用铅芯叠层橡胶支座后具有明显的隔震效果,能有效减轻水平地震作用,从而得到一些有意义的结论。更多还原

【Abstract】 Basic requirements and difficulties in the base-isolated design of high-rise building as the basis,using the finite element analysis software SAP2000 to make a dynamic time-history analysis of some high-rise Frame-shear Wall Structure on different waves.Then the story displacement and the largest shear force of each floor between the base-isolated structure and base are given and compared.The analysis indicate that Frame-shear wall base-isolated structure using lead laminated rubber bearings core have obvious isolated effect and it can effectively reduce the horizontal earthquake effect.Some useful results and conclusions are given.更多还原
