摘　　要：广州科学城中心项目1#塔楼主体结构高120.500m,采用框架-剪力墙结构体系,属于B级高度超限超高层建筑。为了研究其抗震性能,采用基于性能的抗震设计方法进行设计,抗震性能目标取C级。针对项目同时存在角部重叠与体型收进不规则情况,同时采用YJK和ETABS两种软件进行结构整体分析,并采用SAUSAGE软件进行动力弹塑性分析,计算结果表明结构在罕遇地震下处于延性阶段,结构抗震性能满足规范要求。The 1# tower of Guangzhou Science City Center project is a frame-shear wall building with a height of 120.500 m, and it belongs to the out-of-code super high-rise building that exceeds the design limit of B-level building height. In order to study its seismic performance, the performance-based seismic design method was used for design, and the seismic performance target was C grade. In view of the existence of overlapping corners and irregular facade setback in the project at the same time, YJK and ETABS software were adopted for the overall analysis of the structure, and SAUSAGE software was used for dynamic elastic-plastic analysis. The calculation results show that the structure is in the ductility stage under rare earthquakes. The seismic performance of the structure meets the specification requirements.
