［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。

Abstract: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.

Keywords:hybrid base-isolation; rubber isolation bearing; viscous damper; sliding bearing; time-history analysis
