摘　　要：宿迁海关大楼采用组合隔震技术,隔震层设置在地下室顶板和首层之间,结构主体17层,属于高层隔震建筑。主要阐述了主体结构的设计、隔震元件的选取与布置、隔震层相关构造以及隔震结构的计算分析。结果表明,相比传统抗震结构,采用组合隔震技术能显著降低上部结构的地震作用,上部结构可按降低1度进行常规设计,经济效益显著。Suqian Customs Building project adopts base-isolation technology,and isolation layer is arranged between the basement roof and the ground floor.The main structure has 17 stories and belongs to high-rise isolated building.The structural design of the main structure,selection and arrangement of isolation components,related structure of isolation layer and computational analysis of isolation structure were mainly described.Compared with traditional seismic-resistant structures,using the hybrid base-isolation technology will reduce the seismic responses of upper structure significantly.The seismic fortification intensity of isolated structures can adopt minus 1 degree,and the economic benefits are remarkable.
