Is it possible to convert surface loads into member loads in RFEM/RSTAB?
RFEM/RSTAB also allows you to generate member loads from surface loads automatically.
You can do it by using planes or cells. Go to the "Tools" menu, point to "Generate Loads" and select "From Area Loads on Members via Plane" or "From Area Loads on Members via Cells".
Depending on the selected command, you have to define a plane by entering nodes, or you select the cells in the graphic. Find more information on the Help menu that you also can access with the F1 key.
