lateraletorsionele
Lateraletorsionele, in English known as lateral-torsional buckling, is a form of instability that can occur in beams or other flexural members when they are loaded in bending. It describes a combined lateral displacement and twist of the cross-section around its centroid, typically on the side of the beam’s compressive flange. This buckling mode reduces the member’s effective bending capacity and can lead to sudden failure if not properly restrained.
The phenomenon is most common in slender steel beams, such as wide-flange I-beams or hollow sections, that
Key factors affecting lateral-torsional buckling include the unbraced length, the torsional rigidity and warping stiffness of
Prevention strategies focus on increasing lateral restraint and torsional stiffness. This can be achieved with end
