Abstract (en)

[origin: WO9316232A1] A system for counteracting wind induced oscillations in a bridge girder (11) on long cable supported bridges has a plurality of control faces (14, 15, 16, 17, 34, 35, 36) which are arranged substantially symmetrically about the longitudinal axis of the bridge. The control faces are adapted to utilize the energy of the wind in response to the movement of the bridge girder for reducing said movement. The control faces are divided into sections in the longitudinal direction of the bridge, and a plurality of detectors (19, 26) are provided for measuring the movements of the bridge girder. A local control unit (20, 25) associated with each control face section is adapted to control the control face section in response to information from one or more of said detectors. In a method according to the invention the control faces (14, 15, 16, 17, 34, 35, 36) are divided into sections in the longitudinal direction of the bridge, and a plurality of detectors (19, 26) measure the movements of the bridge girder, following which a local control unit (20, 25) associated with each control face section controls the control face section in question in response to information from one or more of said detectors.
