Research Abstract

In order to suppress wind-induced vibrations of bridge girders, two general methods are applied: aerodynamic and mechanical countermeasures. In this study, a new approach to suppress wind-induced vibrations, "a dielectric barrier discharge (DBD) plasma actuator", was investigated through wind tunnel experiments to determine its potential as a device for flow control around bridge deck sections. In this study, it was found that there is a possibility that DBD plasma actuators could be used in the future as the devices for suppressing wind-induced vibrations of bridge girders.
