| Abstract: | On the basis of structural dynamic analysis, regarding the vehicle and the bridge as a combined vibration system, the vibration response of an arch truss composite steel bridge with a 144 192 264 192 144m span under high speed moving train loads is analyzed. The influences of the train speed on bridge deflection, vehicle comfortability and safety are also studies. |
