【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]:China Jiaotong International Center is located on the eastern side of Hanzhou Road, Central Business District, Tianfu New District, Chengdu City. The project site is commercial facilities land, with a total construction area of 159972m2, 39 floors above ground, and a total structural height of 213.1m, of which the main concrete body is 170.3m high. Above is 40 m high steel structure tower crown. The main body adopts the cast-in-place reinforced concrete frame-core tube structure system. The structure belongs to the super-high-rise building with the height of Class B. At the same time, there are some unfavorable conditions, such as discontinuous floor, inclined column, through-story column, and so on. In addition, the structural difference between the roof and the main tower has brought some difficulties to the structural design. The static elastic and dynamic elasto-plastic time history analysis of the structure is carried out by using the performance-based seismic design method according to the relevant requirements of the seismic code and various methods for calculating and analyzing, and the dynamic elastic-plastic time history analysis of the structure is made. The corresponding anti-seismic measures are put forward to provide reference for the design of similar structures.
