Investigation Concerning Vibration Reduction of Self-Anchored Suspension Bridge under Vehicle Braking Forces
Large longitudinal displacement would be generated by vehicle braking force in the girder of self-anchored suspension bridge, just as the floating system of cable-stayed bridge. In this paper, taking Pingsheng bridge as an engineering example, the vehicle braking force models are established according to traffic survey, furthermore dynamic response and vibration reduction of the bridge under vehicle braking force are investigated by finite element analysis. The results show that the longitudinal displacement of the girder is relatively large, and it can effectively be controlled by viscous dampers with optimal parameters.
