Wind load on flexible bridge structure has various structural effects. Catastrophic effect because of wind load which is called flutter phenomenon will make structural failure rapid. Resonance induced vibration is the other wind load phenomenon which not only includes catastrophic failure but has a long-term effect and discomfort effect because of the structural vibration. Vortex is a typical rotational flow in the wake of an obstacle. The flow fluctuates in such a pattern which is known as Von Karman Vortex trails. If the frequency of vortex fluctuation coincides with one of the flexible structure natural frequency, a resonance phenomenon occurs. The phenomenon is called Vortex Induced Vibration (VIV). Vortex induced vibration depends on the natural frequency of the structure, dynamic wind load, and geometry of the structure. VIV can make the bridge vibrate with large amplitude and it can make the structure failure, if the VIV phenomenon occurs in the long period and the structure cannot withstand the dynamic load. It is very important to reduce the vibration when the VIV occurs in the flexible bridge. This paper presents the use of the Tuned Mass Damper (TMD) to reduce vibration because of vortex induced vibration at a flexible bridge. By using wind tunnel test and finite element analysis, the research shows that passive TMD is effective to reduce the vibration at flexible bridge when the VIV occurs. The highest vibration reduction occurs when the frequency of TMD coincides with the frequency of force vibration.
