Living Load Nonlinear Analysis of Self-Anchored Cable-Stayed Suspension Bridges

Abstract:

Living load nonlinearity of self-anchored cable-stayed suspension bridges is studied in this paper. A self-anchored cable-stayed suspension bridge with a main span of 800m is analyzed with linear theory, second-order theory and nonlinear theory respectively. The moments and displacements of both the girder and the pylon under live load are acquired. Based on the results it is derived that the second-order theory can be adopted to analyze a self-anchored cable-stayed suspension bridge with a main span of 800m and the error is less than 6%.
