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.

In the case of using the slow‑curing concrete (usually for thick components), you can reduce the calculated minimum reinforcement by a factor of 0.85 to apply the load due to restraint, according to EN 1992‑1‑1, Section 7.3.2.
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.
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
Is it possible to specify shrinkage effects as loads?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The four plates, identically loaded, show different negative moments at the point of support. Is this a mistake?
- How is the static depth d calculated in the bending design of block foundations (calculation as equivalent beams)?
- Is it possible to set parameters for shrinkage and creep calculation in RF-CONCRETE Members?
- I would like to convert the load from a surface load to a line load, that is, to apply it to the individual beams. How can I do this without using an auxiliary area?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
