Corrugated Web Beams

Hey an interesting Topic....

Light Gauge Corrugated Web Beams:





corrugated web beams have been in development, especially in Germany and Austria, which resulted in their use in a number of applications from supporting roofs and floors to columns. Light gauge corrugated web beams are fabricated beams using thin gauge (2mm, 2.5mm and 3mm thick) sine curve corrugated web welded to wide plate flanges. As a result of its profiling, the web does not participate in the longitudinal transfer of bending stresses. Therefore, in static terms, the corrugated web beam behaves similar to a lattice girder, in which the bending moments and applied forces are transferred only via the flanges, while the transverse forces are only transferred through the diagonals and verticals of the lattice girder, in this case the corrugated web.

The main benefits of this type of beams are that the corrugated webs increase the beam’s stability against buckling, which may result in a very economical design via the reduction of web stiffeners. Furthermore, the use of thinner webs results in lower material cost, with an estimated cost savings of 10-30% in comparison with conventional fabricated sections and more than 30% compared with standard hot rolled Universal beams.
