摘　　要：长兴县行政服务中心工程采用了竖向构件较少落地的大型复杂箱形转换结构。基于确定的抗震性能化设计目标,分别采用振型分解反应谱法、弹性时程分析和pushover分析方法对该工程进行抗震性能研究。根据计算分析结果对转换层结构采用型钢混凝土梁及上下两层混凝土楼板组成的型钢混凝土箱形转换结构,使其在满足建筑造型的同时能达到"小震不坏、中震可修、大震不倒"的抗震设防要求,保证结构足够的安全性,实现了抗震性能化设计目标。The large and complex high-rise structure with box transfer story, vertical members with less ground are employed for Changxing Government Affair Service Center. The seismic performance design objective was determined, and then the seismic performance studies were conducted by response spectrum analysis, elastic time-history analysis and pushover analysis respectively. To achieve three-level performance target of ＂ no damage under minor earthquake, repairable under moderate earthquake,no collapsing under major earthquake＂ ,the box transfer structure with steel reinforced concrete beam and two-layer concrete floors are employed for the structure. Through above series of research, the seismic performance design objective is realized for the building.
