【摘要】 对大型复杂钢结构施工过程中存在的力学问题进行了剖析,探讨了解决这类问题的思路和方法。针对CCTV新台址主楼"塔楼倾斜"、"空间连体"及"大悬臂"的构成特点,通过施工分析给出了结构在施工过程中的安装变形预调值以及幕墙的变形情况,作为主楼施工及安装的重要依据。
【Abstract】 This paper pointed out many mechanical problems encountered during the construction process for a large and complex steel structure,and their solving methods were outlined and discussed.For the new CCTV headquarters,the deformations produced due to the inclined towers and cantilevered structure system during the construction process were analyzed and traced according to the specified construction approach and sequence,and they have been used as guidelines for the steel structure erection and construction,as well as for glass curtain wall design and erection.
【Key words】 steel structure； construction process； the new CCTV headquarters； pre-set deformation value；
