Helpful Questions & Answers

  • Frequently Asked Questions (FAQs)

What are the options in RFEM or RSTAB for determining the ideal elastic critical moment for any cross-sections and systems/loads?
Is it also possible to design flat steel (brackets, flat steel stringers of staircases)?

Answer

For a stability analysis of any cross-section, the add-on modules RF‑/STEEL EC3 Warping Torsion (extension for RF‑/STEEL EC3) and RF‑/FE‑LTB (stand-alone module) are particularly suitable.
By using the calculated critical buckling value, you can determine critical loads and perform the design according to the second-order analysis.
