Lateral-Torsional Buckling and its Influence on the Strength of Beams [E21a]

This lecture will begin by presenting and dissecting the solution to the differential equation that defines the elastic lateral-torsional buckling (LTB) strength of beams. Related flexural and torsional concepts, including the benefits of warping resistance, will be briefly reviewed. The assumption of elastic behavior will then be relaxed to define the inelastic LTB and plastic moment capacities of flexural members. The strength of beams without slender elements will be covered and ultimately presented in the form of beam resistance curves.

This course is based on a past NASCC session.
