Wind-Tunnel Tests of a Bridge Model with Active Vibration Control

The application of active control systems to reduce wind vibrations in bridges is a new area of research. This paper presents the results obtained from a set of wind-tunnel tests on a bridge model equipped with active movable flaps. Based on the monitored position and motion of the deck, the flaps are regulated by a control algorithm so that the wind forces exerted on them counteract the deck oscillations.
