Abstract:
The finite element software Midas Civil was used to develop a three-dimensional model of a practical CFST tied arch bridge with a main span of 85 m over the main canal of the South-to-North Water Diversion Project. Based on the results of moving load analysis and dynamic characteristic property calculation, the load test plan of the bridge was proposed. According to the load test and theoretic analysis of the whole bridge, the design and construction quality of the bridge were tested, and the load bearing capacity of the bridge structure was evaluated. The load test method presented in this paper can provide the basis for the evaluation of the same type of bridges over the main canal of the South-to-North Water Diversion Project.
