In addition to the main programs RFEM 5 and RSTAB 8, which are used to determine internal forces, support reactions and deformations, there are the add‑on modules available, which can perform design according to a specific standard, for example.
The internal forces and deformations from the main program are automatically adopted and further processed in an add‑on module.
The main programs can also be extended with add‑on modules, such as RF‑/DYNAM Pro or RF‑STABILITY, which increase the scope of functions. Most add‑on modules have their own graphical user interface where the standard-specific conditions are taken into account.
