| Abstract: | This paper based on Xi Qiao bridge, Finite element software MIDAS/CIVIL was used to build up a modal. In this modal, the writer analysed the deflection, stress and natural vibration of Steel Box Girder Cable-Stayed Bridge with Single Tower. The result shows that: under the design load the maximum deflection and stress is less than code values, the bending moment distribution is well, and have a certain stress safety margin. |
