| Abstract: | This paper based on Shengli bridge, by using finite element software MIDAS/CIVIL build up a modal, analysis the deflection, stress and natural vibration of completed concrete filled steel tubular arch bridge. The result show that: under the design load the maximum deflection and stress is less than code values, the bridge is safety. |
