某高层混合结构冬季施工分析与验算

ANALYSIS AND CHECKING OF WINTER CONSTRUCTION OF A HIGH-RISE HYBRID STRUCTURE

针对某高层混合结构冬季施工的特点,将理论分析和施工实践紧密结合,在进行详细的施工阶段理论分析及验算的基础上,判断主体结构在钢骨柱和钢骨梁未浇筑混凝土的情况下,能够进行安全施工的最大楼层层数,且通过对应力比较大和稳定性较差的钢骨构件进行局部加强,确保钢骨结构在冬季能够顺利施工,对高层混合结构在冬季施工具有一定指导意义。

This paper described the analysis and checking results of the winter construction of a high-rise hybrid structure,and determined whether it was possible to ensure the safety of the main structure in the case of reinforced column pouring concrete and reinforced beams according to the basis of theoretical analysis and checking of constructing, quality assurance construction maximum floor as well. Local reinforcement were adopted to ensure the smooth construction of the steel structure in winter through steel components with large stress and poor stability. This paper provided reference for winter construction of high-rise hybrid structure.
