| Abstract: | According to energy analogy method, this paper calculates the strain energy of the box girder deck under vehicle load, obtains the stiffness factors of the analogy simply-supported orthotropic plate. Then, the transverse distribution influence-line of the analogy plate can be calculeted using G-M method. And the load distribution width of the box girder deck is derived. Finally two calculating examples are given, and some characters of its are put forword. |
