For this purpose, a member is defined in the area of a slab, which initially rests in the plane of the slab. In the detailed settings of the "Rib" member type, further entries are possible and required for the member: in the "Edit Rib" dialog box, you can enter the rib position (top/bottom) and specify the integration width of the surfaces.
Using these entries, it is possible to design the rib as a downstand or upstand beam with effective slab widths in RF‑CONCRETE Members.
The rib is intended to be used primarily in concrete design. On the other hand, an eccentrically connected member should be used for welded steel ribs on steel surfaces.

The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.

If I do not specify any basic reinforcement in RF-CONCRETE Surfaces, I get the value X as additionally required reinforcement. If I enter this value X as the existing basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why?
