为研究巨型钢框架-预应力拉索支撑结构施工,设计了8种施工方案。对8种施工方案下结构的变形和内力以及索力作对比分析,同时将上述结果与一次性加载方案进行比较分析。结果表明:结构内力和变形以及索力因施工方案的不同而有差异;部分方案下结构内力和变形以及拉索内力较小。分析结果可为巨型钢框架-预应力拉索支撑结构的施工提供参考。
In order to study the construction of giant steel frame-prestressed cable support structure, eight kinds of construction schemes were designed. The structure deformation, internal forces and cable forces under 8 kinds of construction schemes were compared and analyzed, and the above results were compared with the one-time loading scheme. The results show that the internal forces and deformations of the structure and the cable forces are different due to different construction schemes. The internal forces and deformations of the structures and the internal forces of the cables are small under some schemes. The analysis results can provide reference for the construction of giant steel frame-prestressed cable support structure.
