Abstract

In this paper the authors present an analysis of the quality and dynamic behavior of trains running across a long span river bridge. Vibration displacement, differential displacement, vibration mode of the train, and the dynamic interaction of the train and the bridge are examined. The authors determine that train performance on the bridge is reduced on girders in the middle of the bridge. Folding displacement at the bridge?s edges was found not to have a significant impact on the train?s performance. The authors also clarify how train running quality under seismic conditions can be improved by increasing the stiffness of piers on the bridge.
