Lateral-torsional buckling (LTB) and flange local buckling (FLB) are investigated as separate and independent failure modes. As a result, the WLB resistance is handled in effect as a cap on the LTB and FLB strengths. WebTwo of the primary factors that affect the lateral-torsional buckling capacity of a beam are the unbraced length and the distribution of bending moment along the member. Effects …

WebLateral torsional buckling may occur in an unrestrained beam. A beam is considered to be unrestrained when its compression flange is free to displace laterally and rotate. When … 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.
