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


The programs of Dlubal Software GmbH are subject to a continuous improvement process so that an improvement executed in this module is not unlikely over a period of about 18 years. It should be noted, however, that a design according to DIN 18800 is not up-to-date anymore, but that it is better to work with the current add-on module for steel design, i.e. RF-/STEEL EC3, according to Eurocode 3.
