| Abstract: | The spatial discretion model is used to calculate the natural vibration properties of the structure of Daxigou Station Bridge on Chongqing Saddle Type Single-Track Light Rail Transit and by means of the load array method of the vehicle and bridge interaction theory, the vibration of the structure under 15 loading cases when light rail vehicles pass through is analyzed. The results show that the structural design of the Bridge is rational, the structure has sufficient rigidity and the global dynamic properties are good, and moreover the vibration on all parts of the Bridge satisfies pedestrian comfort. |
