Comparison of Analytical and Numerical Methods Applied to Lateral Torsional Buckling of Beams

The paper is focused on the numerical evaluation of transversally loaded beams of one symmetric and four asymmetric cross-section shapes susceptible to lateral torsional buckling. Several analytic methods used for evaluation of the beam bending resistance in design software were evaluated. Analytic methods and results are compared to each other and finite element models using shell and solid elements.
