| Abstract: | In this paper,the problem of the impact coefficient of an infinite numder degree of freedom spring quality model of the beam bridge at the moving vehicle is presented. The influences of the dynamic behavior of free beam under condition of varied span length and speeds of moving vehicle are studied. This research reveals the change regular patterns of the impact coefficienf of the beam bridge at the moving vehicle loads. |
