箱拱单肋合拢中缆风索的受力分析

Research on the Force Analysis of the Guy Cable in Single Rib Box Arch Closure

在缆索吊装单肋合拢施工中分析风载及缆风索对箱型拱肋的影响,利用数学和力学关系推导出单肋合拢施工中缆风索的受力简化模型,计算出缆风索的等效弹性刚度。总结缆索吊装单肋合拢时设置缆风索注意事项,为单肋合拢缆风索的设计与施工提供依据。

In the RC box arch ribs closure of single,guy cable is a major stabilization measure in the closure of a single rib cable erection.This paper analyzes the arch rib impacted by the wind load and the guy cable in the closure of a single rib cable erection.The simplified model in construction are deducted by making use of mechanical and geometrical relationship in the closure of a single rib cable erection,calculate the equivalent elastic stiffness of the guy cable.The question established the guy cable are also summarized,which can be referenced to the construction In the RC box arch ribs closure of single.
