The bridge vibration problem would be highlighted due to flexibility of bridge when traffic is run on the long-span & high-tower continuous rigid-frame bridge. The finite-element (FE) software of bridge-vehicles coupling vibration theory was utilized to analyze traffic load influence on bridge vibration. It is found that the vehicle accelerations are varied greatly in the middle of mid-span and edge of side-span and vehicle bodies are plunged. According to the evaluating indicator of comfort level, people feel sea-sickness when vehicles run in design speed with fundamental frequency. Due to fundamental frequency of body in different speed, the sea-sickness feel will be stronger with lower speed. The impact action can be decreased by the increase number of vehicle-line load, and it is affected by the distance of vehicle-line load. |
