WebJan 1, 2013 · The distance of transverse load from shear centre axis may significantly affect the buckling resistance of a simply supported beam. When transverse concentrated load W acts at (Yq-Yo) below the shear centre and moves with the beam it acts as an additional torque W(Yq-Yo) about shear centre which opposes twist and increases resistance to … 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.
