Study on the Calculation Method of the Transverse Distribution of Load of the Continuous Precast Fabricated Girder Bridge

In order to provide the theory gist of the transverse distribution of load of the continuous precast fabricated girder bridges. Based on equivalent simple beam conversion rigidity law basic principle, the traditional revision rigid crossbeam principle, the hinged girder principle, the rigid connected girder were used to the calculate transverse distribution of load of the continuous precast fabricated girder bridges, then analyzing contrast results that the traditional load transverse distribution calculation method and the space finite element method. According to the cause of the error has been analyzed of the traditional load transverse distribution calculation method contrast with the space finite element method, the suitability and the accuracy of the traditional load transverse distribution calcu- lalion method have been demonstrate.
