Abstract:
By analyzing all kinds of analysis theory of cable stays, the problems about cable stays were divided into two kinds, and based on the theory of catenary cable element, a unified analysis theory of cable stays was put forward. It could solve almost all static problems about single cable stay accurately and consistently. Authors made it easy to apply the catenary element to analysis of cable-stayed bridges. Based on the theory of catenary cable element and equivalent modulus of elasticity, cable characteristics which had different length and different stress were studied comparatively. It was concluded that nonlinearity of cable stays became more significant dramatically when its length exceeded 400 m. The error of the method of equivalent modulus of elasticity may be very large. Some kinds of errors can not be decreased even increase the number of load steps. It is recommended to use catenary cable element in the analysis of super long span cable-stayed bridges.
