Westok cellular beam design software8/30/2023 ![]() ![]() Vierendeel mechanism and web post buckling (WPB) are examples of failure modes originate due the openings, while already existing failure modes on solid beams are modified in cellular beams, such as lateral-torsional buckling (LTB). The presence of the opening influences in the failure modes of the beam. ![]() This type of beam is increasingly used because it is capable to support long spans, it can have a bending resistance up to 2.5 times higher than its parent section and its openings allow the passage of technical equipment and ventilation systems through their web, which reduces the floor height and therefore the overall height of building. The procedure results in a deeper beam, approximately 40-60% deeper than its parent solid section. Porto, PortugalĬellular beam generally originates from steel hot-rolled I-section member, which the web is cut, displaced and subsequently welded (Westok method) to obtain openings in the web spaced regularly, with different forms like circular, sinusoidal or hexagonal, see Figure 1.
