Research on the Load Distribution Coefficient of Cable-Stayed Bridge with Long Cantilever Structure Based on Full-Scale Test

Abstract

This paper is focused on the load distribution problem, which is especially concerned in design phase, for a long cantilever steel-concrete composite cable-stayed bridge with single tower and single cable plane. A large scale full-scale test is performed to make a systematical study on the load distribution coefficient under different conditions. A refined finite element model is gained by FEM software ANSYS to obtain the theoretical results, which are compared with measured data in model test. Finally, a suggested value of the coefficient is drawn through the test result.
