In spite of having defined average regions, they are not considered in the design in RF‑CONCRETE Surfaces. What setting did I miss here?


To consider the average regions in the design in RF‑CONCRETE Surfaces, it is always necessary to activate them in the detailed settings of the add-on module. For this, see Figure 01 with the detailed settings in RF‑CONCRETE Surfaces.

In the design in RF‑CONCRETE Surfaces, the average regions are considered for the ultimate limit state design (ULS) as well as for the analytical calculation of the serviceability limit state (SLS).
