Abstract: Process for reinforcing a construction structure where, laid on one portion of said structure, is at least one portion of a reinforcement (10) of elongated shape comprising continuous fibers in the longitudinal direction of said reinforcement, which are combined with a polymer matrix, wherein said process comprises a step of removing the polymer matrix in one portion (20) of the reinforcement so as to release the fibers of the reinforcement in order to allow their rearrangement following their release from the polymer matrix. It is thus possible to optimize the binding configuration of the reinforcement with a portion of the structure to be reinforced.

Abstract: A method for transporting a civil engineering structure including a mast in an aquatic medium is presented. In an embodiment, the method includes fastening the civil engineering structure to at least one flotation unit, moving the civil engineering structure and the connected flotation unit in the aquatic medium as far as a desired position. The civil engineering structure may be fastened to the flotation unit in a region situated above the center of equilibrium of the civil engineering structure connected to the flotation unit. The connection may be configured to uncouple the rotational movements of the flotation unit and of the civil engineering structure about at least one axis perpendicular to the longitudinal axis of the mast of the civil engineering structure.

Abstract: The invention relates to a method for determining the fatigue capital of a cable supporting a civil engineering structure, the method including: a measuring step (S1, S2) during which the normal tensile stress in the cable and the bending stress in the cable are measured in a synchronized manner so as to obtain the compound stress in the cable; a counting step (S3) during which a count of the number of stress cycles, depending on the amplitude of the stress, is carried out from the measured compound stresses; and a step (S4) of assessing the fatigue capital of the cable during which the fatigue capital of the cable is determined by comparing the count, carried out in the counting step, with a pre-set Wohler curve for the cable.

Abstract: The anchoring device for a cable made of plurality of tendons comprises an anchor block having a front side, a rear side and channels extending between the front and rear sides, each tendon of the cable being received in a respective channel with a blocking member. It also comprises a first protective material with which at least some of the channels of the anchor block are filled, a chamber containing portions of the plurality of tendons of the cable, located on at least one of the front and rear sides of the anchor block, and a second protective material, different from the first protective material, with which the chamber is filled.

Abstract: The method is for protecting the end of a cable made of a plurality of parallel tendons (10) anchored using a block (15) having a front side, a rear side and channels (16) extending between the front and rear sides. Each tendon of the cable is held in a respective channel of the anchor block with a blocking member (19). The method comprises performing a first phase of injecting protective material (100) into at least some of the channels of the anchor block. A chamber (30) is formed on at least one side of the anchor block (15) so as to contain portions of the plurality of tendons. A second phase of injecting protective material (200) into the chamber (30) is then performed.

Abstract: The prestressed building structure comprises an assembly of precast elements separated by gaps occupied by an interface product, one or more prestressing sheaths having sections respectively incorporated into the precast elements, and a prestressing tendon tensioned inside the sheath. The sheath sections are respectively fitted with first and second end pieces opening out on the facing surfaces of the two precast elements. The first end piece has a flared opening. An elastic connecting sleeve is connected in a sealed manner to the second end piece. The sleeve presses against the first end piece, which compresses it longitudinally to ensure a seal between the inside of the sheath sections and the gap separating the adjacent surfaces of the two elements.
