I have designed a steel column with the RF‑/KAPPA add-on module in RSTAB, Version 4. When designing the steel column in Version 8 of RSTAB now, I get more cost-effective results. What could be the reason for this?


The programs of Dlubal Software GmbH are subjected to a continuous improvement process, so that the improvement in this module is not improbable over a period of about 18 years. However, you should note that the design according to DIN 18800 is not up-to-date anymore, and it is better to work with the current add-on module for steel design, RF‑/STEEL EC3, according to Eurocode 3.
