Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, members (beams), solids, and contact elements.
Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, and truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
RF-/STEEL performs general stress analysis of members and surfaces by calculating the existing stresses and comparing the results with limit stresses.
The following add‑on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as deformation analyses for structural steel.
Design general cold-formed sections according to EN 1993-1-3 and EN 1993-1-5 with the RF-/STEEL Cold-Formed Sections module extension and the SHAPE-THIN cross-section program (from version 9).
RF‑/STEEL Warping Torsion is an extension of the RF-/STEEL AISC and RF‑/STEEL EC3 add‑on module. It performs flexural-torsional and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.
RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module. It allows for plastic design of cross‑sections according to Partial Internal Forces Method or Simplex Method.
RF-STABILITY/RSBUCK determines buckling modes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behavior.
RF-IMP/RSIMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.
RF-/STEEL Fatigue Members performs fatigue design of members (beams) and sets of members in compliance with the standard EN 1993‑1‑9.
CRANEWAY calculates and performs all required designs of craneway girders according to Eurocode 3. Optionally, you can select bridge or suspension crane.
Stand-alone software PLATE‑BUCKLING or add-on modules RF‑/PLATE‑BUCKLING perform plate buckling analysis of rectangular plates according to EN 1993‑1‑5.
Stand-alone cross‑section analysis software SHAPE‑THIN determines cross-sectional properties, performs stress analysis and plastic design of any thin-walled cross-section. It is possible to export cross-section and calculated section properties to main programs RFEM or RSTAB.
Add-on modules for dynamic analyses are suited for seismic design, vibration analysis of buildings, machine foundation design, natural frequency analysis for bridges and chimneys, and many other dynamic calculations.
Here you can find numerous add-on modules for the design of joints in steel and timber structures.

The member hinge nonlinearities "Scaffolding - N phiy / phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.
The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.
