摘要：

The dynamic interaction between high-speed train and simply supported girders is studied by theoretical analysis and field experiment in this paper. The dynamic interaction model of the train-bridge system is established, in which the rigid-body dynamics theory, finite element method and wheel-rail displacement corresponding assumption are adopted for the vehicle model, bridge model and wheel-rail interaction model, respectively. The measured track irregularities are taken as the system excitation. The responses of a 24 m-span PC box girder bridge are calculated. The proposed analysis model and the solution method are verified through the comparison between the calculated results and the measured results. (c) 2007 Elsevier Ltd. All rights reserved.
