Answer:
In RFEM and RSTAB, it is possible to define load and result combinations manually and otherwise. The combinations can also be generated automatically according to the requirements of German and international standards. To do this, select the "Generate Combinations Automatically" option in the General Data dialog box of the model and specify the standard; see Image 01.
To generate the combinations, it is necessary to assign the load cases to actions that comply with the standard. The program then automatically creates all possible load or result combinations according to the selected standard.
It is often not necessary to consider all generated load or result combinations. Therefore, they can be reduced before the calculation (automatically or manually; see Image 02 and Image 03) so that the computing time is reduced.
