【Abstract】 Based on theory of nonlinear FEM, the internal force and deformation of a cable bridge during static loading test is analyzed in this paper. The deformations due to some load conditions are measured and they are compared with theoretical solution by the method mentioned above. The results can tell us the mechanical property of the bridge structure, and provide a basis for safe usage of the bridge.更多还原
