Is there a module for automatic creation of action combinations?

Answer

In RFEM and RSTAB, it is not only possible to manually define load and result combinations. The combinations can also be created automatically according to the requirements of the 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 Figure 01.

Figure 01 - Edit Model - General Data

For the generation, the load cases must be assigned to actions that comply with the standard. The program then automatically creates all load or result combinations that are possible 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 Figure 02 and Figure 03) so that the computing time is reduced.
