［摘要］锦江文创产业中心塔楼建筑高度217.8m，主体结构总高度为193.55m，大屋面以上为异形钢结构塔冠，采用钢筋混凝土框架-核心筒结构体系，属于超B级高度且包含楼板不连续、局部不规则、扭转不规则三项不规则项的超限高层建筑。介绍了项目特点和结构体系的选择，针对超限情况提出了相应的抗震措施，采用ABAQUS软件对结构进行了大震动力弹塑性分析，对穿层柱屈曲分析、塔冠钢结构稳定性设计等专题进行了探讨。分析结果显示，穿层柱屈曲分析建议采用结构整体模型，结构各项性能指标较理想，整体设计满足规范要求。

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.
