How can I perform a lateral-torsional buckling analysis for unsymmetric steel cross-sections?

Answer

In this case, it is recommended to use the module extension RF‑/STEEL Warping Torsion:

RF-/STEEL Warping Torsion is an extension of the RF-/STEEL EC3 and RF-/STEEL AISC add-on modules. It performs flexural-torsional (flexural-torsional) buckling analysis of members according to the second-order theory with seven degrees of freedom and application of imperfection with regard to mode shape.
