Definitions

  • the present invention relates to a bridge comprising at least one upper member in concrete and one lower member in concrete or metal connected to each other by structural elements resistant to shearing forces.
  • the two members of the bridge transmit the moments, while the structural elements or webs arranged between these members transmit the shearing forces.
  • the cores are constituted by a series of bars arranged according to an N. Some of these bars work in compression and others in traction.
  • the members and the webs can be made of concrete and / or steel.
  • the cores arranged between the frames are constituted by elements made of pleated sheets. These pleated sheets are discontinuous, that is to say separated from each other along the length of the bridge.
  • the object of the present invention is to create a bridge which withstands very large cutting forces, while being of light construction and easy to implement.
  • the bridge comprising at least one upper concrete member and one lower concrete or metal member connected to one another by structural elements resistant to shearing forces is characterized in that these structural elements comprise two continuous steel sheets, folded or corrugated, arranged on either side of a median vertical plane of the bridge, the folds or corrugations extending in a direction substantially perpendicular to the length of the bridge.
  • the invention makes it possible to produce a bridge capable of withstanding significant shearing forces by using light pleated sheets which are therefore easy to implement.
  • the continuous sheets comprise two series of flat strips located in two parallel planes, the strips of one of the series being connected to the strips of the other series by flat strips forming an angle with the latter, the junction between the strips being constituted by an edge.
  • This structure gives the pleated sheet excellent resistance to shearing forces, even when this sheet has a thickness reduced to a few mm.
  • the thickness of the sheets is between 8 and 12 mm
  • the amplitude of the folds is between 10 and 30 cm
  • the dimension of the sheets measured in the direction of these folds is between 2 and 12 m.
  • the bridge according to the invention comprises an upper member constituted by a concrete slab 1 and a lower member constituted by a beam 2 made of concrete or metal or by a metal tube filled with concrete connected to the slab 1 by two continuous and pleated steel sheets 3, 4 arranged on either side of a median vertical plane P of the bridge, the folds or undulations extending in a direction substantially perpendicular to the length of the bridge.
  • the assembly constituted by the slab 1, the beam 2 and the pleated sheets 3,4 rests on concrete pillars 5 by means of lateral studs 6 extending between the slab 1 and the beam 2.
  • the continuous sheets 3,4 each comprise two series of flat strips 7, 8 situated in two parallel planes, the strips 7 of one of the series being connected to the strips of the other series by flat strips 9 forming a certain angle a (equal to 37 ° in the example shown) with the latter, the junction between the strips being constituted by an edge.
  • the thickness of the sheets 3, 4 can vary between 8 and 12 mm
  • the amplitude A of the folds 7, 9; 9, 8 can vary between 10 and 30 cm and the size of the sheets measured in the longitudinal direction of these folds can vary between 2 and 12 m.
  • the width of the strips 7, 8, 9 can vary between 0.25 and 0.50 m.
  • the assembly constituted by the slab 1, the two pleated sheets 3, 4 and the lower beam 2 forms a tubular structure of constant triangular section. Since the pleated sheets 3, 4 are continuous, the lateral surface of the above-mentioned assembly is completely closed.
  • the upper and lower members are constituted by concrete slabs 10, 11. These are connected to each other by two pleated sheets 3, 4 identical to those of the embodiment according to FIG. 1.
  • each pleated sheet 3, 4 has at each of its edges adjacent to the slabs 10, 11 a plate 12, 13 perpendicular to the general plane of the sheet 3, 4 and projecting from both sides. other of this plan.
  • These plates 12, 13 comprise on their face facing outwards, a series of metal connectors 14 embedded in the concrete of the slabs 10, 11.
  • the sheets 3, 4 are firmly anchored to the slabs 10, 11.
  • connection mode can also be adopted in the case of the embodiment according to FIG. 1.
  • the continuous sheets 3,4 are generally not made in one piece along the entire length of the bridge. These sheets are preferably constituted by pleated sheet elements made in one piece in the direction perpendicular to the length of the bridge and fixed to each other in the length direction of the bridge by welding, riveting, bolting or the like.
  • FIGS. 4 to 17 have in common the fact that the upper chord is a concrete slab 1, 15.
  • the lower members consist of two metal beams 16 ( Figures 4, 5) or concrete 17 ( Figures 6, 7), the pleated sheets 3, 4 being perpendicular to the slab 15 .
  • two additional pleated sheets 18, 19 extend respectively from the edges of the sheet 3 adjacent to the slab 15 and to the beam 16 or 17 by forming a dihedral whose apex is located in the vertical plane P of symmetry of the bridge.
  • Figures 8 and 9 are cross-sectional views of the embodiment shown in Figure 1.
  • Figures 10 and 11 are similar to Figures 8 and 9. The difference is that the concrete beam 20 which constitutes the lower member is hollow and has a diameter greater than that of the beam 2 of Figures 1, 8 and 9 .
  • the lower chord is constituted by a concrete slab 21, 22, 23, 24, 25, 26 of variable width, less than that of the upper slab 15, the pleated sheets 3, 4 arranged symmetrically on either side of the vertical plane P of the bridge, forming a certain angle with this plane.
  • the shear forces give rise to a uniform field of shear stresses t.
  • the dimensioning of such a structure consists in checking that the shear stress t is less on the one hand than the buckling stress tv with a suitable safety coefficient k, and on the other hand than the admissible shear stress tm for l steel, either:
  • Condition (4) is more severe than condition (1), but for bridge cores it is condition (6) which strongly penalizes discontinuous cores.
  • This continuous pleated sheet core can withstand a shearing force T c which is worth: from where:
  • the core elements are subjected to bending moments M which are maximum at the ends where they are worth:
  • a core of continuous pleated sheet metal in accordance with the present invention can transmit a shearing force more than eight times greater than that which a core of discontinuous pleated sheet metal can transmit.
