We provide hints and tips to help you get started with the main programs RFEM and RSTAB.
For load combination, RSTAB and RFEM automatically perform the second-order analysis. Which criteria are used here? Can I deactivate this?
In the result combinations, the results of the load cases and load combinations are just "brought together." You get an envelope of the internal forces (max and min values).
For load cases and load combinations, you have the option to specify the method of analysis in the "Calculation Parameters" dialog box (menu "Calculation"). You can calculate load cases and combinations by three methods separately. Because in result combinations the results of load cases and/or load combinations are evaluated, the result combinations can therefore contain results according to statically linear, second-order, or large deformation analysis.
For load cases and load combinations, the results are always unambiguous internal forces. For more information, see chapter 5.5 of the RSTAB or RFEM manual.

Your support is by far the best
“Thank you very much for the useful information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. In the industry of structural analysis, I use several software including service contract, but your support is by far the best.”
