【摘要】 运用ANSYS程序对某一12层框架结构进行了模态和地震时程分析,为体现分段隔震结构的隔震效果,对比了分段隔震与基础隔震的地震反应;同时也对分段隔震结构在双向和单向水平地震作用下的地震反应进行了分析和对比;提出了结构在双向地震作用下整体位移最大值的计算方法,结果表明分段隔震结构比基础隔震能更有效减小结构的地震反应.更多还原

【Abstract】 A modal analysis and a seismic time history analysis are performed on a twelve-story frame structure by using ANSYS program.In order to know the isolation effect of the segmented structure,the seismic responses of the segmented structure and the base isolation structure are compared.At the same time,the seismic responses are analyzed and compared,while the segmented isolation structure is subject to bilateral and unidirectional earthquake excitations.The method to calculate the overall maximum displacement with the structure subjected to bilateral earthquake excitations is put forward.Results show that the segmented isolation structure can more effectively reduce the seismic responses of the structure than the base isolation structure.更多还原
