| Abstract: | 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. |
