高层框—筒混合结构施工期间变形控制策略

On deformation control strategies in construction period of high-rise frame-cylinder structure

结合钢框架—核心筒混合结构在施工阶段的受力特点和施工特点,建立了确定核心筒领先钢框架施工层数的方法,提出了结构体系减小竖向变形差的设计构造策略,以期指导工程实践。

By combining with the stress characteristics and construction features of the frame-cylinder structure in the construction stage,the paper establishes the methods to identify the construction storey numbers of the core cylinder advanced steel frame,and points out the design strategy to reduce the vertical deformation of the structure,so as to direct the engineering practice.
