Answer:
In RFEM 5, it is possible to design surfaces and members made of reinforced concrete: The members are designed in the RF‑CONCRETE Members or RF‑CONCRETE Columns add-on module, and the surfaces are designed in the RF‑CONCRETE Surfaces add-on module (optionally with RF‑CONCRETE Deflect or RF‑CONCRETE NL).
Thus, reinforced concrete solids cannot be designed directly in RFEM 5—there is no add-on module for reinforced concrete design of solids.
However, it is possible to create solids with the "Concrete" material and determine the stresses within the solid, for example. Optionally, you can also insert a result beam into the solid, with which the results of the solid are converted into member internal forces. You can then subsequently design the result beam in the add-on modules RF‑CONCRETE Members or RF‑CONCRETE Columns.
