Vibration Control of Bridge for Serviceability

This paper mainly propose the new passive vibration control device, named BRV(the bridge reduced vibration), for reducing excessive traffic-induced vibration of bridges and for measuring performance of BRV numerical example was simulated. The purpose of BRV is mainly on reducing vertical acceleration and displacement of bridge. In BRV we can control the stiffness and damping coefficient to accept the performance we want. The result of simulation showed that the vertical acceleration and displacement was effectively diminished. It would be concluded that BRV can be used to improve the serviceability of bridge and fatigue life etc.
