| Abstract: | In the paper,one of the finite element analytical models for spatial vibration of the train and deck steel plate girder bridge system is presented.The computer simulation methods are adopted and the spatial vibration responses are calculated when the train runs through the deck steel plate girder bridges of 32m span at high speeds in order to test if the bridges have sufficient rigidity and operation stability.The results coincide with the field test data and provide reference for policy making departments. |
