| Abstract: | Based on the theories of structural mechanics and random process, the relations among the impacting coefficient, the dynamical property of vehicle and bridge and the plainness of bridge surface are analyzed. A new method is put forward for calculating the impacting coefficient. The simularities and differences between the bridge design codes and the method in this paper are discussed. |
