Dynamic Behavior of Railway Bridge Due to Trains Moving on Double Tracks

복선선로를 통과하는 열차에 의한 철도교량의 동적거동

In this study, the simplified method for 3-dimensional vehicle-bridge interaction analysis is utilized in the analysis of dynamic behavior of bridges in which the eccentricity of axle loads and the effect of the torsional forces acting on the bridge are included for the more accurate vehicle-bridge interaction analysis. Investigations mainly into the influence of vehicle speed on vehicle-bridge interactions are carried out for case that two trains move respectively on their tracks in the opposite direction.
