摘　　要：杭州秦望广场项目T2塔楼采用框架-核心筒结构,屋面高度为205.20 m,为B级高度建筑,同时存在扭转不规则、裙房偏心率大于0.15、楼板不连续、斜柱四项不规则,需要进行超限设计。论文对该结构进行了小震、中震和大震作用下的结构分析,分析结果表明,整体结构能满足预先提出的性能目标要求。针对不规则项,针对性地采取了抗震构造措施,以保证结构安全。The T2 tower of Hangzhou Qinwang Square project adopts the frame-core tube structure,and the roof height is 205.20 m,which is a B-level height building.At the same time,there are four irregular torsion,skirt eccentricity greater than 0.15,floor discontinuity and inclined column,so over-limit design is needed.The analysis of the structure under small shock,medium shock and large shock shows that the whole structure can meet the proposed performance target requirements.For the irregular items,the seismic structural measures are taken to ensure the safety of the structure.
