ACTIVE FLUTTER AND BUFFETING CONTROL BY WINGLETS

摘要

The alternative solution for flutter and buffeting stability of a long suspension bridge will be an active control using winglets. This method enables a light weight economic stiffening girder without an additional stiffness for aerodynamic stability. The numerical study and wind tunnel test on the flutter and buffeting control by winglet which placed at the both side of a bridge deck show that the flutter and buffeting can be suppressed through the adequate motion of winglets.
