Structures

Level structures

  • A bigger stiffness in comparison with RC beams of the same carrying capacity and depth
  • A smaller number of the pillars, although keeping the girders included in the thickness of the floor
  • Smaller section of the beams in comparison with RC beams of the same span
  • Shorter execution time
  • Safer laying, even if implemented by unskilled staff
  • Immediate free room on the floor for further activities

Vertical structures

  • Aseismic dissipative reaction
  • Smaller dimensions in comparison with RC pillars
  • Structural homogeneity using mixed structure beams
  • Complete integral relation between horizontal and vertical load bearing structures
  • Easy laying of the beams

“NOR” , “CLS” Our Technology Beams

It is composed of a metal trestle with a variable number of stringers and cores, as well as a lower plate being the active reinforcement of the beam and serving as caisson and bracket for the floor. It is finished with Our Technology® “TRC” trestles mounted on the pillars, absorbing the fixed end moments and save the structure of the beams in time.

The Our Technology® “NOR” Beam with no plate can be partly pre-cast while in machine shop, thus becoming Our Technology® “CLS” Beam.

“TRC” Our Technology Trestle

They replace the additional FeB44k stump-reinforcements, with a triple advantage for the user:
a mixed structure even level with the panel points, taking advantage of the relevant mixed-structure standards; a guaranteed higher level of safety as for fixed ends; elimination of any manual operation about laying the stumps.

“TR” Our Technology Beam

They are modular beams: according to static requirements, they come out of the placement side by side of several self-bearing reticulated standard trestles; extending some of them aside an adjacent line girder, the structural continuity by the panel points is guaranteed. Provided with a steel plate or a concrete slab, “TR” Our Technology® Beams serve as bearing for the floors, supporting their competence weight too. But if provided with cross stiffening brackets, they are put directly on the floors or in the caissons, as in the traditional building method. The “TR” Our Technology® beam, as finished with the concrete slab or put in caissons while still in progress, gets REI 180 (The resistance fireproof time).

“DIS” Our Technology Beam

The Our Technology® misaligned beam excludes all additional reinforcements as the trestles get over the panel point for all the required length in order to take up directly the thrust against the shearing stress and the negative moments.

Our Technology® Lumbers

As natural pairing of Our Technology® Beams, the Our Technology® Lumbers permit the execution of totally self-bearing level planks by use of the ordinary lifting gears in the yard. The Our Technology® lumber is reinforced with trestles linked one another by windbracing devices, avoiding any event of lateral warping of the upper stringer. The part made of concrete, englobing the welded wire nettings and the braces, is normally 4-6 cm thick, according to the required REI class.

Steel tubular column

Tubular metal piers filled with concrete provide reduced building material, shorter planting and laying time and reduced space requirements. The progressive tapering of tubular thickness at the higher levels of the structure helps maintaining the external dimensions unaltered at all levels. The special flanged ends of beams and the patented joint system provide structural continuity both vertically and horizontally at the junction with Our Technology® beams. Joints are designed to provide easy and rapid installation with effective load transfer onto the pier.

Our Technology Pillar

The reinforcement of Our Technology® pillar is made of a vertical trestle anchoring to the girders of the floor by means of 2 horizontal trestles that are aside the beams in the panel points, so they can get, once englobed in the final casting, the integral relation between horizontal and vertical load bearing structures. The vertical trestle is composed of several bayonet joints pitching level with no-moment point. The upper lap of each part projecting over the flat, that has no core on one direction in order to receive the beams inside, will be then closed by the second reticular element put on it

Sismi Our Technology Structural panel point

Sismi Our Technology® panel point, put on the flange level with the flat, is used inside the steel tubular pillars with a concrete casting in order to implement the integral relation between horizontal and vertical load bearing structures. Sismi Our Technology® panel point, as inserted in the intersection zone between girder and pillar in order to control local effects of stress diffusion, provides an effective aesismic dissipative reaction, and it can also link self-bearing beams in both directions.
