Definitions

  • the invention relates to an earthquake-resistant metal frame consisting of columns and profiles, possibly provided with concrete.
  • the computational forces representing the action of an earthquake on a construction are in a given geographical area and for a given structure - proportional to the mass of the construction - function of the vibratory characteristics of the structure (natural periods) - dependent on the capacity of the structure to absorb the energy of the earthquake in stable mechanisms, of the plastic patella type, called "dissipative zones".
  • the Calculation Codes define a certain number of conditions to be respected in order to be entitled to the weakest calculation forces and, consequently, to the lightest structures. These conditions relate to - the topology of the structures, - the section slender sections and - the dimensions of the assemblies; these must be such that the dissipative zones are located outside the assemblies, because the latter are generally incapable of developing a stable and ductile plastic mechanism.
  • R fy represents the plastic moment M p of the bars.
  • R fy is the normal plastic force N p of the bars. This is a very restrictive condition, leading to costly assemblies, difficult if not impossible to achieve.
  • the object of the invention is to propose a metal frame having excellent behavior during an earthquake while being light, of simple and economical construction.
  • Figs. 1 and 2 there is a column 1 connected via an end plate 2 to a beam 3.
  • the connection end plate-beam is usually made by welding while the end plate is bolted to the column.
  • a Code requirement requires that the dissipative zones be located in the beams and not in the columns.
  • the section of the beam near the assembly 4 has been reduced over a length 1 equal to the height h of the beam. This length is in fact the minimum length necessary for the formation of a plastic ball joint.
  • the extent of the shrinkage 5 can be worth around 30% of the width b of the beams' wings.
  • the minimum distance from the start of the narrowing to the assembly 4 is of the order of a quarter of the width of the wings of the beam.
  • the reduction in effective cross-section of the beam can also take the form of a reduction in cross-section by drilling or by punching multiple holes 6, as shown in FIG. 3.
  • a part of a trellis structure is distinguished.
  • the stretched diagonals 42 are made with angles.
  • the upper frame 41 constituted by U-shaped profiles, is connected by means of a gusset 43 and angles 44 and 45 to the column 40.
  • the invention here takes on a particularly elegant appearance by providing a reduction in section 46 in the stretched diagonals 42 intended to constitute a dissipative zone which is reliable in traction.
  • a dissipative zone can be provided towards each end of the stretched diagonals. For reasons of economy of manufacture, they are only provided near one of the ends, in general that which is fixed to the upper chord.
  • the stretched diagonal 42 has a reduction in effective section due to a multitude of holes 47.
  • Fig. 6 shows a simpler trellis structure, in which the upper member 41 is directly fixed to the gusset 43. Similarly, the gusset 43 is directly welded to the column 40.
  • the reduction in effective section 48 here consists of an ellipsoidal cut in the edge of one of the two wings of each angle. One can also perform a less pronounced removal in the two wings of an angle.
  • the proposed solution leads on the one hand to a loss of useful cross section of the diagonals which can reach 50%, but the reduction factor on the design forces is 4 if the lattice structure can be considered dissipative.
  • the overall result therefore remains a reduction in the steel used for the diagonals by a factor of the order of 2.
