Abstract
The invention provides a construction comprising a structural element and at least one cable (101) arranged in tension to carry at least a part of the weight of the structural element. The cable defines an outer surface (102) onto which at least one strake (104) forms a protrusion for reducing rain and wind induced vibrations. The strake has a height being a distance from a strake root part connected to the outer surface of the cable and a strake end part terminating the strake outwards away from the cable, and the strake has a width being transverse to the height, the width decreasing in the direction from the strake root part towards the strake end part. The height is less than 5 percent of the diameter of the cable. Furthermore, the strake comprises a first strake surface portion facing away from the cable, which first strake surface portion is concave or straight.
