[摘要] 昆山创业园大厦1#办公楼结构高度143m,为B级高度的超限高层,采用钢筋混凝土框架-核心筒结构体系。采用SATWE进行弹性时程分析。整个结构及构件设计融入了性能化设计思想,主要抗侧力构件满足中震不屈服(局部构件中震弹性)设计目标,并对结构进行大震下的pushover分析。

Abstract: Kunshan Enterprise Zone Mansion is a high-rise building of B-level height with 143m height,the structural system is frame-core wall concrete structure. The elastic time history analysis was used under frequent earthquake by SATWE. The performance-based seismic design principle and method were applied in the structure design. The main vertical lateral members did not yield under medium earthquake, and part of the vertical lateral members remained elastic under medium earthquake. Pushover analysis under rare earthquake was also done.
Keywords: super-tall structure; time history analysis; performance-based seismic design; pushover analysis
