Abstract
The most widely used calculation method for bridge transverse distribution coefficient based on plate theory is G-M method. The twisted parameter and bending stiffness parameter are firstly obtained in its calculation process, the distribution coefficient can be determined through inquiring the tables established by Guyon and Massonnet. The work for this computation is huge and the errors are inevitably exist in the stage of inquiring tables. Therefore, an analytical method is proposed in this paper, the partial differential equations of deflection surface can be acquired through analysis and corresponding calculating program is prepared. Numerical simulation of simply supported bridge is presented for validating its feasibility.
