Abstract

The calculation methods of transverse load distribution coefficient based on beam system theory include hinge method and rigid connected beam method. The calculation process is complicated and can usually be used through special tables. However, the traditional tables for ten beams can not satisfy the design requirements with the development of transportation. Therefore, a series of simple and practical analytical formula are proposed based on finite difference method. A numerical simulation of simply supported beam bridge is used to verify the effectiveness of the proposed method. The results reveal that the proposed method possesses favorable accuracy.
