| Abstract: | In this paper, the along-wind and across-wind responses of suspended cables are studied. The mean wind direction is assumed to be perpendicular to the plane of the suspended cable. It is shown that the cable gallops in the across-wind direction, when the mean wind speed exceeds a critical wind speed. To control the galloping response, a vertical viscous damper, in the vertical plane of the cable, is introduced at a certain location on the cable to a near fixed platform such as a bridge deck. The efficiency of the vertical viscous damper and its location in controlling the galloping of the suspended cable is investigated. |
