However, you can solve this problem if you do not model the downstand beams as rib members, but replace them with a surface model. Thus, the entire slab can be modeled as a surface structure and designed with RF‑CONCRETE NL in RF‑CONCRETE Surfaces.
Question
How can I design a slab with downstand beams in RF‑CONCRETE NL? I would like to know the deformations in cracked state. However, this does not seem to work with the entered rib members. Is there any alternative input option?

Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
In RFEM 6 and RSTAB 9, you have the option to enter "Visual Objects" as guide objects. You can import the file formats 3ds, stl, and obj.
These objects allow you to create a better reference to the dimensions.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
