摘要
对处于7度烈度区的某平面不规则多层结构进行了隔震分析设计,隔震层主要由普通橡胶支座、铅芯橡胶支座组成,为控制隔震层水平位移,可布置粘滞阻尼器。对该结构的时程分析结果表明:采用组合隔震措施可以显著降低上部结构地震响应,同时也可以很好控制隔震层位移。
This paper is focused on the design of an asymmetric building which is located at the area assessed as intensity of seven degrees. The isolation layer is mainly composed of linear rubber bearings and lead rubber bearings. To decrease the horizontal displacement of the isolation layer, viscous dampers are applied simultaneously. The time history analysis of the structure indicates that the composite isola- tion scheme can significantly decrease the response of superstructure, and meanwhile control the displacement of isolation layer.
