Definitions

  • the present invention relates to composite beams for the construction industry.
  • composite beam is understood herein to mean: (i) a beam, preferably formed from steel, and (ii) a solid slab or a composite slab; that are interconnected by shear connection to act together to resist action effects as a single structural member.
  • shear connection is understood herein to mean an interconnection between a beam and a solid slab or a composite slab of a composite beam which enables the two components to act together as a single structural member under the action effect of bending which causes longitudinal shear forces to develop.
  • the shear connection includes shear connectors, slab concrete, and transverse reinforcement .
  • shear connector is understood herein to mean a mechanical device attached to a beam (typically to a top flange of the beam) which forms part of the shear connection.
  • the present invention relates particularly, although by no means exclusively, to composite beams of the type which include:
  • a horizontal beam typically steel
  • a composite slab that is positioned on and supported by the beam and includes:
  • profiled metal (typically steel) sheeting having a plurality of pans separated by ribs, the profiled sheeting being positioned in relation to the beam so that the ribs are parallel to the longitudinal axis of the beam or the ribs and the longitudinal axis of the beam describe an acute angle of less than or equal to 15°;
  • the present invention is concerned with overcoming a major problem that occurs with composite beams of the type described above that include conventional welded stud shear connectors and profiled steel decking having open metal ribs.
  • the problem is a complex type of longitudinal shear failure involving lateral rib punch- through failure that has been studied by the applicant in research work that has been carried out by the applicant.
  • An object of the present invention is to provide a composite beam with improved resistance to longitudinal shear failure involving lateral rib punch-through.
  • a composite beam which includes:
  • a reinforcing component embedded in at least one concrete rib that includes embedded shear connector or connectors the reinforcing component being in the form of a mesh that includes line wires and cross wires that are connected together at the intersections of the wires.

  • the mesh be positioned so that the line wires extend in the longitudinal direction of the concrete rib, ie in the longitudinal direction of the beam.
  • the purpose of the cross wires is to take tension forces and balance transverse components of shear connector reactive forces that develop in the base region of the shear connector or connectors .
  • line wires One purpose of the line wires is to anchor the cross wires so that the cross wires can take tension forces.
  • line wires Another purpose of the line wires is to balance the longitudinal components of shear connector reactive forces that develop in the base region of the shear connector or connectors .
  • the mesh be positioned in the concrete rib between 25% and 75% of the height of the concrete rib.
  • the composite slab includes profiled metal sheeting having a plurality of metal pans separated by metal ribs and concrete cast on the profiled sheeting.
  • the metal pans and the sides of the metal ribs define the outer surfaces of the concrete ribs .

  • the beam be a steel beam.
  • the profiled metal sheeting be profiled steel sheeting.
  • the beam be supported at each end.
  • the beam may be supported also at one or more locations along the length of the beam.

  • shear connectors there may be more than one shear connector at each location along the length of the beam.
  • the shear connectors may be arranged in pairs along the length of the beam.
  • the spacing between the shear connectors along the length of the beam be no more than 7.5 times the height of the shear connectors above the top of the concrete ribs. This maximum spacing avoids having to use a reinforcing component of the type described in Australian patent application 69998/01 in the name of the applicant in the composite beam.
  • the top of the concrete ribs is taken to be the top of the adjacent metal ribs .
  • the reinforcing component be a flat sheet of welded wire mesh that includes a rectangular array of parallel line wires and cross wires welded together at the intersections of the wires .
