ABSTRACT

Based on the rigid-jointed beam method for calculating the transverse load distribution, using an analytical method for calculating the transverse load distribution of low box girder bridges is proposed in this paper. In the field test and the evaluation of bridge bearing capacity, the numerical calculation method of finite element model can be replaced, which provides a more accurate theoretical reference for the field test of prefabricated PC box girder bridge and the evaluation of bridge technique condition and bearing capacity. In order to verify the correctness of this method, this paper takes a 20m span prefabricated box girder bridge as an example, and verifies the correctness of this method by comparing the analytical calculation method and the field test results.
