PURPOSE:To produce a vibration-damping cable prepared by providing rugged parts on a surface-coated cable for a suspension structure to prevent vibration thereof and capable of reducing the wind load acting on the cable. CONSTITUTION:In a cable 3 prepared by applying an anti-corrosive coating 2 to the surface of a cable composed of many cable strands 1, assembles 4 or 5 each composed of many circular or polygonal depression parts 4a or projection parts 5a are made in lines or at random on the coated surface. Distortion of the wind is generated by these rugged parts and vibration of the cable 1 can be prevented thereby. The total area of the rugged parts is controlled to 10 to 30% based on the unit surface area of the cable so as to prevent increase of the drag coefficient of the cable and, therefore, there is no fear about increase of the wind load acting on the cable. |
