深圳能源集团总部大厦项目由南、北塔楼及连接南北塔楼的连桥组成,北塔楼主体结构高208.5m(整体结构高宽比约为6.8,核心筒结构高宽比为17),南塔楼主体结构高100m,南北塔楼在2~9层通过连桥连接,属于复杂高层建筑。北塔楼结构体系采用了较为成熟且已在多项工程应用的框架体系+核心筒+加强层架的多重抗侧体系。主要介绍了连桥与南北塔楼连接方式以及腰桁架、伸臂桁架设置位置的研究,并提出这些主要抗侧力构件满足中震弹性(不屈服)设计目标,特殊重要构件满足大震性能目标。动力弹塑性时程分析进一步验证结构在大震下的整体性能要优于不倒塌要求。
The project of Shenzhen Energy Group Headquarters consists of the south and north towers and the connecting bridge connecting the north and south towers. The main structure of the north tower is 208.5m high (the overall structure aspect ratio is about 6.8 and the core tube structure aspect ratio is 17) Structure 100m high, North and South towers in the 2nd to 9th floor through the bridge connection, are complex high-rise buildings. The North Tower structural system uses a more mature and has a number of engineering applications in the framework of the system + core tube + multi-layered anti-side reinforcement system. The connection between the bridge and the north and south towers and the location of the waist trusses and the boom truss are mainly introduced. The design goals of the mid-spring elastic (non-yielding) are also proposed, and the main components of the main anti-side members meet the target of large earthquake performance. Dynamic elasto-plastic time-history analysis further verifies that the overall performance of the structure under earthquake conditions is better than that of non-collapse.
