What are the options for determining the elastic critical buckling moment for any cross-sections and systems/loads by means of RSTAB or RFEM?
Is it also possible to design flat steel (brackets, flat steel side walls of stairs)?

Answer

For the stability design of arbitrary cross-sections, the add-on modules RF-/STEEL EC3 Warping Torsion (add-on module for RF-/STEEL EC3) and RF-/FE-LTB (stand-alone add-on module) are particularly suitable.

By using the calculated critical value, you can determine branch loads and perform a design according to the second-order analysis.
