Abstract:The height of Jinjiang Cultural and Creative Industry Center tower is 217.8m, and the total height of main structure is 193.55m. The  special-shaped steel structure tower crown is above the large roof. The strcuture adopts  reinforced concrete frame-corewall structural system. It belongs to the out-of-code high-rise building with  exceeding B-level height  and includes three irrengular items, such as the floor slab discontinuity, local irregularity and torsion irregularity. The characteristics of the project and the selection of the structural system were introduced, and the corresponding seismic measures were put forward according to the out-of-code situation. The dynamic elastic-plastic analysis of the structure under the rare earthquake was carried out by using ABAQUS software, and the buckling analysis of the cross-story columns and the stability design of the tower crown steel structure were discussed. The analysis results show that the overall structural model is recommended for buckling analysis of the cross-story columns,  performance indexes of the structure are ideal, and the overall design meets the requirements of the code.

Keywords:frame-corewall structure; super high-rise building; cross-story column; buckling mode analysis; steel structure tower crown; stability; dynamic elastoplasticity
