| Abstract: | SAP93 is an excellent ViziCAD processing system. A prestressed continuous box girder bridge is analysed by using finite element method. Through the analysis of test result, it is concluded that the test method is reliable and feasible, the actual force and deformation is less than design value. The results of finite element calculating are in agreement with the test results, which shows the feasible test scheme and the test data. |
