Abstract: Bridge truss, bridge span including such trusses, and method of constructing the truss. Prefabricated transverse sections of a bridge are essentially constituted by a three-dimensional truss of prestressed high mechanical strength concrete without a deck. The prefabricated sections are placed in situ to build up a bridge span, and deck-constituting units are subsequently placed on the span after it has been assembled. The invention also provides the unit three-dimensional trusses constituted by bars (P1 to P30) of prestressed high mechanical strength concrete interconnected by assembly blocks cast in concrete. The invention is particularly applicable to bridge building using the cantilever technique and a guyed support beam.

Abstract: A bridge has prefabricated sections and is prestressed externally of the concrete of the sections by cables. Each section has upper and lower decks, interbraced by longitudinal oblique webs which form dihedrons. Certain dihedrons are closed by transverse panels. The panels assure the desired deviations of the prestressing cables as well as their anchoring.

Abstract: The invention relates to a cable. The cable consists of a tubular shell forming a double hoop around a concrete mass which fills the shell and which has at least one longitudinal passage in the concrete for a prestressing cable. The invention applies in particular to cables for producing anchorage lines, bracing and bridge-supporting cables.
