Abstract
The invention proposes a device for damping the vibrations of a cable used in the structure of a construction work, the cable comprising a bundle of metal strands having ends anchored to the work and being surrounded, in at least one region adjacent to an anchored end of the bundle, by a tube connected to the work, the device comprising a collar placed around the bundle of strands and means of absorbing the vibration energy mounted substantially between the collar and the tube, wherein the absorption means comprise at least two piston-type dampers with substantially linear stroke, placed substantially radially relative to the cable and distributed at angles around the cable, each piston-type damper having a first link articulated with the collar and a second link articulated with a support secured to the tube.
