［摘要］普陀龙湾项目1号塔楼19层和2号塔楼18层连接形成连体结构。两栋塔楼高度不同，为非对称双塔连体结构，主体采用框架-剪力墙结构，连体部分采用钢空腹桁架。介绍了项目的工程概况、结构整体设计指标、连体结构的设计要点，并对多程序的计算结果进行分析对比。结构设计融入了抗震性能化的设计思想，对连体部分舒适度、构件受力进行了细致的分析。罕遇地震作用下，对结构进行了弹塑性动力时程分析。分析结果表明，结构主要抗侧力构件满足中震不屈服（关键构件在中震作用下保持弹性）的抗震性能目标，结构各项指标均满足规范的要求。

Abstract:The 19th floor of tower 1 and the 18th floor of tower 2 are connected to form a connected structure for putuo Longwan Project. The two towers have different heights and are asymmetric double-tower connected structures. The main body adopts a frame-shear wall structure, and the connected part adopts a steel open-web truss. The project′s engineering overview, overall structural design indicators and design points of the connected structure were introduced, and the calculation results of multiple programs were analyzed and compared. The structural design incorporated design ideas for performance-based seismic design, and a detailed analysis of the comfort degree of the connected parts and the stress on the components was conducted. The dynamic elastic-plastic time-history analysis of the structure was performed under rare earthquakes. The analysis results show that the main lateral force-resisting members of the structure meet the seismic performance target of non-yield (the key members remain elastic under the action of fortification earthquakes), and all the structural indicators meet the requirements of the code.

Keywords:out-of-code connected high-rise structure; comfort degree analysis; performance-based seismic design; dynamic elastic-plastic time-history analysis
