| Abstract: | Shawang bridge is take of for study to establish two stage's FEM models of this bridge by the Dr Bridge program-the maximal cantilever construction stage and the completed stage.The main girder and mail tower's sensitivities are analyzed by taking changes of the parameters of cable force,in addition to propose the trend and cause of the structure.The valuable conclusions can provide the reference to the design and construction of similar bridges. |

| Keywords: | cable-stayed bridge with low tower cable force sensitivity parameter |
