This series of videos teaches the calculation of buckling load for a simply supported beam under a distributed load. As you may have noticed, Eurocode does not provide an equation for critical bending moment in lateral torsional buckling calculation. This video demonstrates how to calculate critical distributed load using a commonly used equation, interpret the results, and compare them with manual calculations and results from Ansys and RFEM.
