Abstract:The special-shaped steel grid structure roof of annex for Suzhou Taiping Finance Tower integrates with the tower exterior wall as a whole to present a soft-silk-like continuous curve shape. Steel grid structure supporting system is composed of sliding bearings on the tower, 4 dendriform columns raised from basement roof, and V-shaped columns on top of  annex roof, and the spatial arrangement is complex. The structural layout and related bearing design were introduced. The dynamic characteristics and the stability of the structure were analyzed. Seismic performance analysis on the key structural members such as dendriform columns was carried out. The finite element analysis was conducted on the key joints. Analysis results indicate that the relevant joint construction can satisfy the requirements of structural safety.

Keywords:Suzhou Taiping Finance Tower; special-shaped grid; dendriform column; stability; joint analysis
