CONSTRUCTION AND A TENSION ELEMENT COMPRISING A CABLE AND A PLURALITY OF STRAKES

摘要

The invention provides a construction comprising a structural element and at least one cable (100) 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 a plurality of strakes (104) form protrusions for reducing rain and wind induced vibrations. Each 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 form the cable, a width being transverse to the height, and a length transverse to the height and width and along which length the strake is connected to the cable. The length of each strake is shorter than the circumference of the outer surface, and the height is less than 5 percent of the diameter of the cable.

1. A construction comprising a structural element and at least one cable arranged in tension to carry at least a part of the weight of the structural element, the cable defining an outer surface onto which a plurality of strakes form protrusions for reducing rain and wind induced vibrations, wherein each 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 form the cable, a width being transverse to the height, and a length transverse to the height and width and along which length the strake is connected to the cable, the length of each strake being shorter than the circumference of the outer surface, wherein the height is less than 5 percent of the diameter of the cable, and wherein the longitudinal direction of the strake extends in a direction substantially orthogonal to the longitudinal direction of the outer surface.
