摘要:	Short overhanging beams usually exist at both ends of a simply supported bridge. As a train passes through the overhanging beams of the bridge at high speeds, the overhanging beams would be subjected to intensive vibrations, from which the dynamic response of the train-bridge system would be built up. To mitigate the amplified response of the train-bridge system due to the overhanging beam effects, an end rotational spring to restrain the relative rotations is equipped between the free ends of the adjacent beams. By the vehicle-bridge interaction finite element analysis, the numerical studies indicated that the overhanging beams play a key role in amplifying the response of the train-bridge system. Even so, the proposed end restraintscan reduce the amplified response of the VBI system significantly
