［摘要］吴江某办公楼为一超限高层建筑，总高度98.28m，所带裙房高度26.23m。存在扭转不规则、楼板不连续、体型竖向收进、塔楼偏置等超限情况。采用了抗震性能化方法对结构各关键构件进行设计；采用了两种软件对主体结构进行小震弹性、中震弹性和不屈服、大震不屈服分析，对薄弱部位采取加强措施。计算结果表明，该结构总体指标均能满足规范要求，可以达到预期的抗震性能目标。

Abstract： The office building in Wujiang City is a high-rise building beyond code-specification and the building′s height is 98.28m, the podium′s height is 26.23m. Some conditions beyond code-specification as follows, reverse, discontinuous floor, vertical structural setback and the bias. Performance-based seismic design method was used to design the key structural members in the engineering, the main structure was analyzed by two software, including elastic analysis under frequently occurred earthquake, elastic and yield analysis under fortification earthquake, yield analysis under rarely occurred earthquake, to take measures to strengthen the weak parts. The results show that the structure can satisfy the requirement of criterions in overall index and can achieve the expected seismic performance objectives.

Keywords: high-rise building beyond code-specification; performance-based seismic design
