Answer:
In this case, "EC2 for RFEM" is not an add-on module that you can run separately, but a standard according to which you can design reinforced concrete structures in RF‑CONCRETE Surfaces or RF‑CONCRETE Members, for example.
The selection of the design standard can be found in the "General Data" dialog box of the respective add-on module.
The same applies to "EC2 for RSTAB".
A design standard, here "EC2", is required in the following add-on modules:
- RF-CONCRETE in RFEM 5
- BETON in RSTAB 8
- RF-/BETON Stützen in RFEM 5 und RSTAB 8
- RF-STANZ Pro (nur für RFEM 5 verfügbar)
