PROTECTION SYSTEM FOR TENSION MEMBERS
A tension member protection system includes two or more shell elements arranged circumferentially around a tension member which together surround a cavity that receives the tension member. A plurality of joining sleeves, each of which is associated with one of the two shell elements, is designed and arranged on the shell elements in such a way that, in a cavity forming state, they interlock so that their through-holes in the longitudinal direction of the tension member protection system only overlap completely when the two shell elements lie with their contact surfaces against other. A rod-shaped element is designed to be passed through the through-holes of the interlocking joining sleeves.
Device for damping vibrations in a cable, notably a cable stay
The damping device comprises: a base comprising a through-orifice for receiving said cable, said through-orifice extending along at least a longitudinal axis, and at least one cylinder connected to said base and inclined with respect to said longitudinal axis at an angle other than 90, and, for said cylinder, a complementary cylinder connected to said base and inclined with respect to said longitudinal axis at an angle other than 90, the cylinder and the complementary cylinder being arranged on either side of a plane orthogonal to the longitudinal axis, the orthogonal plane containing a centre of the base, said centre being situated along the longitudinal axis.

DOUBLE-SHEATHED STRUCTURAL CABLE
The structural cable comprises a bundle of load-bearing tendons extending between upper and lower anchoring devices, a first sheath containing the bundle of tendons, and a second sheath arranged around the first sheath, with a gap between the first and second sheaths.

STRUCTURAL CABLE HAVING AN INNER HOUSING
The structural cable of a construction work comprises a bundle of load-bearing tendons, a sheath within which the bundle of tendons is located, and at least one vibration module received within the sheath and configured to generate vibrations to break superficial ice or frost deposits on the cable.

Device to provide protection of a structural member against a cutting threat
A device to protect a structural member against a cutting threat, such as a saw blade or thermal cutting device, is provided. The device provides a substrate having a cavity disposed therein. A cutting resistant element is disposed within the cavity to impede cutting of a cutting device, such as a saw blade or thermal cutting device, into the cutting resistant element.
Parallel wire cable
A parallel wire cable is produced from a plurality of wires arranged in a bundle for use as a structural cable. Each wire in the plurality of wires is parallel to every other wire in the bundle, and each wire in the plurality of wires is tensioned to a tension value.
