［摘要］本工程为高位大跨连体超限高层建筑，两侧塔楼房屋高度均为137-050m，属B级高度，连接体位于32层～屋面层，跨度为29-600m。基于抗震性能设计方法，采用YJK，ETABS软件对结构进行了多遇地震作用下的弹性分析，采用YJK软件对结构进行了设防地震作用下的性能分析，采用SAUSAGE软件对结构进行了罕遇地震作用下的弹塑性时程分析。分析结果表明，结构可满足预定的抗震性能目标，设计时针对结构薄弱部位采取相应的加强措施。

Abstract:It is an out-of-code high-rise building with large-span high-position connected structure. It belongs to level-B height high-rise building by code with building height of 137-050m. The connected part is located on the 32th floor to the roof floor, and the span is 29-600m. Based on the performance-based seismic design method, the elastic analysis of the structure under the frequent earthquake was carried out by YJK and ETABS software. The performance analysis of the structure under the intermediate earthquake was carried out by YJK software. Elastic-plastic timehistory analysis was carried out by  SAUSAGE software under the rare earthquake. The analysis results show that the structure can meet the predetermined seismic performance targets, and corresponding reinforcement measures in the design  should be taken for the weak parts of the structure.
