| Abstract: | Aiming directly at frequently occurred vehicle and bridge collision,the analysis model of vehicle and bridge impact dynamics was established according to falling-weight impact equipment on the reinforced concrete pier model.Based on the D’Alembert principle,the Single-Degree-of-Freedom and Two-Degree-of-Freedom models were set up for one-dimensional and double-dimensional conditions to calculate impact force.The results show that the errors of peak and average were-15.4% and 14.5% respectively.It can provide the significant reference for anti-crash of bridge. |
