| 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. |
