Abstract: The total building height of the main tower of Suzhou Zhongnan Center is 499. 15m, and its structural system is amega frame⁃core tube⁃outrigger truss system. The main structural characteristics and relevant load values of SuzhouZhongnan Center tower were emphatically expounded, the seismic analysis method and seismic performance objectives of thetower were introduced, and the seismic action analysis in the elastic stage was carried out. At the same time, theapplication of additional damping system, high⁃strength concrete and outrigger truss in this project was also introduced. Theanalysis results show that all the indexes of the structure meet the requirements of the code, and the structure design is safeand reliable.
