The free vibration characteristics were tested, and the dynamic responses of strains, displacements, swings and accelerations were also tested under the dynamic loads of the train passing through the bridge with different uniform velocities and with the train braking at some special points on the bridge with some required velocities. Comparison between the testing results and the calculated results with regard to the vehicle-bridge coupling vibration was made. Test results indicate that the bridge is of favorable vertical and transverse stiffnesses and structural strength; the passing train has some impacting function on the bridge, however, the passing train has good safety and comfort performance.Read More
