If you define an average region in parts of a surface in RFEM, the internal forces are shown as averaged in this region. These averaged internal forces are not automatically applied for the design in RF‑CONCRETE Surfaces.
To carry out a design with averaged internal forces, open the "Details" dialog box of RF‑CONCRETE Surfaces and select the option indicated in the image.
This option is available for the ultimate limit state design (ULS) as well as for the analytical method in the serviceability limit state (SLS).
