［摘要］中交国际中心位于成都市天府新区中央商务区汉州路东侧，项目用地为商务设施用地，总建筑面积为159972m2，地上39层，结构总高213.1m，其中混凝土主体高170.3m，以上为40m高的钢结构塔冠。主体采用现浇钢筋混凝土框架-核心筒结构体系，结构属于超B级高度的超限高层建筑，同时存在局部楼层楼板不连续、斜柱、穿层柱等不利情况，此外位于屋顶的塔冠采用钢结构门式造型，其与主体塔楼的结构差异给结构设计带来了一定的难度。通过多种方法手段进行计算分析，结合抗震规范的相关要求，采用了基于性能的抗震设计方法，对结构进行了静力弹性以及动力弹塑性时程分析，并提出了相应的抗震加强措施，为同类结构的设计提供了参考。

Abstract： CCCC International Center is located in the eastern side of Hanzhou Road of Chengdu Tianfu new area’s central business district. The land is used for commercial facilities, and the total construction area is 159,972 square meters, 39 layers on the ground. The structure total height is 213.1m, of which the main concrete high is 170.3m. 40m high steel tower crown is on the top of main concrete structure. The frame core-tube system is applied in the upper structure, and the structure belongs to the super class B out-of-code high-rise building. Local floor slab discontinuity, inclined column and cross-pillar exist in the structure. Tower crown adopts steel structure with door type, hence, different structure between main body and tower crown brought certain difficulty to structure design. Through a variety of calculation and analysis method, based on the relevant requirements of seismic code, the seismic design method based on the performance and static flexibility and dynamic elastic-plastic time history analysis were applied to analyze the structure model, then, some corresponding seismic strengthening measures were applied to the structure, and references were provided for similar structure design.

Keywords: out-of-code high-rise building; performance-based design; elastic-plastic analysis
