Stress Analysis Software
Structural FEM Analysis and Design
The structural analysis software RFEM 6 is the basis of a modular program family. You need the main program RFEM 6 to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Is your project diverse? Dlubal structural analysis programs too! Therefore, you can create combined structures as well as to model solid and contact elements.
Structural Frame & Truss Analysis Software
Do you primarily work with beam, frame, and truss structures? We recommend you the structural frame & truss analysis software RSTAB 9. With RSTAB 9, you get a similar range of functions as with the structural FEA software RFEM. However, due to the special attention to beam, frame, and truss structure, RSTAB is very easy to use. Just because of its ease of use and the supreme reliability, RSTAB 9 has been the best choice for structural analysis and design of pure structural member models for many years.
Add-ons and Add-on Modules for RFEM and RSTAB
Do you want to use special materials in your project? For design of various materials, such as reinforced and prestressed concrete, steel, aluminum, timber, and glass, there is a wide range of powerful add-ons and add‑modules. You can thus choose exactly the add-ons you need for your project.
Use these add-on modules and add-ons to easily perform nonlinear calculations, stability and dynamic analyses, joint design checks, and form‑finding processes for cable and membrane structures. Take your time to look around our selection.
Stress Analysis of Pipelines
Without the appropriate software, it is difficult to estimate how much stress a piping system can withstand. The RF‑PIPING Design add-on module for RFEM 5 compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1, and ASME B31.3. This is an easy way to ensure that you meet all necessary requirements when planning your project.
The calculation in the add-on module is done on the basis of the piping modeling in the RF‑PIPING add-on module for RFEM 5.
Interfaces for Data Exchange
Dlubal structural analysis software is innovative in all respects. For example, it can be seamlessly integrated into the Building Information Modeling (BIM) process. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.
Use the Webservice (a programmable interface) for this. Thus, you will be able to read or write the data from or to RFEM and 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 modules. What is the reason?
- How does the "Orthotropic Plastic" material model work in RFEM?
- Why cannot I define a rotation when defining layers?
- Why does the load wizard "Member Load from Area Load" give unnecessary concentrated loads?
- In the case of stairs with a complicated geometry, it is often difficult to design welds by using the analytical methods. How can I do this with RFEM?
- The limit stress is activated, but my stress ratio is “non-designable” in the Stress-Strain Analysis add-on. What could be the reason?
- Is it possible to calculate the weld stresses between surfaces with RFEM 6?
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
- For the settlement calculation in the RF‑SOILIN add-on module, the specific weight gamma and gamma,sat are required for the soil. What do I need the value gamma,sat for, and how is it assumed in the calculation?
- I would like to define a line support with ineffective tension and apply the tension force on this line using a nodal support instead. Why does the line support still receive a tension force?
