Stress Analysis Software
3D Finite Element Analysis and Design
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 and members. The program also allows you to create combined structures as well as model solid and contact elements.
Analysis & Design of Frame/Beam/Truss Structures
Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analyses.
Add-on Modules for RFEM and RSTAB
For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add‑modules available for the main program RFEM/RSTAB.
These modules allow you to perform nonlinear, stability and dynamic analyses as well as joint designs and form‑finding processes for cable and membrane structures.
Piping Stress Analysis
RF‑PIPING Design compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1, and ASME B31.3.
Design in RF‑PIPING Design is based on pipeline modeling in RF‑PIPING.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

Classification and Ultimate Limit State Design of SHAPE-THIN Cross-Sections
When designing a steel cross-section according to Eurocode 3, it is important to assign the cross-section to one of the four cross-section classes. Classes 1 and 2 allow for a plastic design, classes 3 and 4 are only for elastic design.
Nonlinear Material Law for Membranes
In RFEM, there is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).
This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
- The design ratio of the cross-section check is different for the RF‑/STEEL and RF‑/STEEL EC3 add-on module. What is the reason?
- How does the "Orthotropic Plastic" material model work in RFEM?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- How can I consider holes in steel members?
- Is it possible to set user-defined values when viewing solid stress results?
- Why is there no stability analysis displayed in the results despite the activation of the stability analysis in RF‑/STEEL EC3?
- After the design with RF‑/TIMBER Pro, I optimized a cross-section. Why is the utilization of the optimized cross-section exceeded now?
- Why are the stresses of the 90° orientation not displayed for a layer with the orthotropy direction 90° for σb,90 in RF‑LAMINATE?
- In RF‑/STEEL EC3, is the "Elastic design (also for Class 1 and Class 2 cross-sections)" option under "Details → Ultimate Limit State" considered for a stability analysis when activated?
- In the RF‑/STEEL EC3 add-on module, I obtain an extremely high design ratio for a member in the case of "Biaxial bending, shear and axial force." Although the axial force is relatively high, the design ratio seems to be unrealistic. What is the reason?
