摘要
苏州中南中心主塔楼总建筑高度为499.15m,其结构体系为巨型框架-核心筒-伸臂桁架体系。重点阐述了苏州中南中心塔楼的主要结构特点及相关荷载取值,介绍了塔楼的抗震分析方法以及抗震性能目标,并对其进行了弹性阶段的地震作用分析。同时还介绍了附加阻尼系、高强混凝土以及伸臂桁架在本工程中的应用。分析结果表明,结构各项指标均满足规范要求,结构设计安全可靠。
The total building height of the main tower of Suzhou Zhongnan Center is 499.15 m, and its structural system is a mega frame-core tube-outrigger truss system. The main structural characteristics and relevant load values of Suzhou Zhongnan Center tower were emphatically expounded, the seismic analysis method and seismic performance objectives of the tower were introduced, and the seismic action analysis in the elastic stage was carried out. At the same time, the application of additional damping system, high-strength concrete and outrigger truss in this project was also introduced. The analysis results show that all the indexes of the structure meet the requirements of the code, and the structure design is safe and reliable.
