Answer:
In RFEM or RSTAB, you can easily display the corresponding support reactions / internal forces in a result combination in tables. This is automatically set by default.
If you want also to display them in the printout report, it is necessary to activate the extreme values in the corresponding tables. You can do this in Selection.
In this example, the extreme values were only activated for the support force Pz, which means that the maximum support forces in the Z direction are displayed with the corresponding support reactions of the other directions.
If you want to include a graphical display, you have to print the graphic of the displayed load cases or load combinations in the printout report.
