C channel lateral torsional buckling

WebReading time: 3 minutes. Lateral torsional buckling is a buckling phenomenon observed in unrestrained beams. When a beam subjected to loads results in both lateral displacement and twisting, then it is said to undergo lateral-torsional buckling. More causes and features of the lateral-torsional buckling phenomenon in beams are explained below. WebApr 1, 2006 · Failure in cold-formed steel beams is generally initiated by one of three instabilities: local, distortional, or lateral-torsional buckling. For cold-formed steel joists, purlins, or girts, when the compression flange is not restrained by attachment to sheathing or paneling, distortional buckling may be the predominant failure mode. Experimental …
