Abstract: The effectiveness of multiple viscous dampers in reducing response of the bridge subjected to earthquake and wind load is investigated. A bridge of span 32 m with an intermediate bent at centre and abutment at the ends, subjected to various loads is analysed in software. The resonant response of the bridge is studied for different loads like wind, earthquakes, and other external forces. In this study, dampers are installed in strategic locations throughout the bridge, and their damping coefficients are adjusted to control the level of vibration. Response of the bridge is also studied for different arrangements of FVDs. Additionally, the location and number of dampers can be optimized based on the specific characteristics of the bridge, such as its size and geometry, to achieve the best performance.

Keywords: FVD – Fluid Viscous Damper, Resonant response.
