| Abstract: | In this paper,the vibration energy dissipation design of a pedestrian bridge with TMD system and fluid viscous dampers installed in bridge middle span was introduced.A TMD system includes a mass of metal and 8 spring dampers.The fluid viscous damper is a kind of velocity related damper without rigidity.The dynamical analysis results proved that the vibration energy dissipation can effectively reduce the resonance response of the bridge. |
