摘　　要：为提升核心筒偏心收进的超高层办公塔楼的结构设计及抗震性能,文中以某城市综合体混凝土框架-核心筒结构项目为例,通过YJK和ETABS软件计算验证整体结构指标,并探讨核心筒在不同荷载作用下的内力分布及加强措施,最终通过动力弹塑性时程分析评估结构在罕遇地震下的抗震性能,确保整体结构及关键构件满足抗震要求。In order to improve the structural design and seismic performance of a super tall office tower with eccentric core tube,this paper takes a concrete frame-core tube structure project of an urban complex as an example,verifies the overall structural index by using YJK and ETABS software,and discusses the internal force distribution and strengthening measures of the core tube under different loads.Finally,the seismic performance of the structure under rare earthquakes is evaluated through dynamic elastic-plastic time-history analysis to ensure that the whole structure and key components meet the seismic requirements.
