Stress Analysis Software
The structural analysis software RFEM 6 is the basis of a modular program family. The main program 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.
The structural frame and truss analysis software RSTAB 9 has similar functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years, it has been the best choice for structural analysis and design of pure structural member models.
For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add-ons and add‑modules.
They allow you to perform nonlinear, stability and dynamic analysis as well as joint design and form‑finding process for cable and membrane structures.
The RF‑PIPING Design add-on module for RFEM 5 compares the existing pipe stresses with the allowable stresses according to ASME B31.1, ASME B31.3, and EN 13480‑3.
This is done on the basis of the piping modeling in the RF‑PIPING add-on module for RFEM 5.
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
For a project in Rotterdam, ADS Ertner used IDEA CONNECTION to analyze a structural steel connection. This program calculates steel connections utilizing the CBFEM method, where each thin-walled cross-section is modeled with nonlinear material properties, nonlinear bolts, and nonlinear welds.
A new research station was built in East Antarctica for the Indian Ministry of Geosciences in the Antarctic summer months of 2010/11 and 2011/12. The design and planning come from the offices of bof Architekten and IMS Ingenieurgesellschaft in Hamburg, Germany.
The complex structure consists of an enveloping steel structure and a total of 134 special containers, which were integrated to transfer vertical and horizontal loads. The final structural analysis was carried out by the German engineering office of KSF in Bremerhaven.
The temporary structure of a steel maze was created to celebrate the 10th anniversary of the C‑Mine arts center in Genk (Belgium), which is located at the former coal mine of Winterslag.
It took almost one month to install the steel structure at the arts center on an area of 15,069.5 ft2.
A glass pedestrian bridge with a length of 98.4 ft connects St. Michael's Hospital with the Li Ka Shing Knowledge Institute research center.
The supporting structure consists of several oval steel rings which are twisted together.
At the end of 2013, the "Vechthoeve" was transported over a distance of 1,640 ft. The wooden house, referred to as the "Pippi Longstocking" house, is situated close to Amsterdam, the capital of the Netherlands. The villa had to be relocated because of plans to widen the A1 highway.
The New Candlewood Suites on Redstone Arsenal in Huntsville, Alabama, is the first cross‑laminated timber (CLT) hotel constructed in the US.
62,930.7 ft³ of cross-laminated timber and 12,925.1 ft³ of glued-laminated timber were used for the four-story hotel with 92 rooms.
The Metropol Parasol is a hybrid structure consisting of timber, concrete, steel, and composite steel.
The most interesting and impressive part of the building is the accessible timber roof structure consisting of multi-layer glued timber panels of LVL type Kerto‑Q.
The steel structure of a sluice with a flap gate is a part of the new Niederfinow boat lift on the east end of the Oder-Havel Canal in Germany.
It was built due to increasing traffic, as the original structure of the oldest working boat lift in Germany was running near capacity.
This project for designing a filter/dryer device, including agitator, required a complete stress and deformation analysis in RFEM.
The complex modeling of the structure, which had 1,424 surfaces, 158 solids, and 425 members, represented a special design challenge.

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.
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?
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?
- Is it possible to consider the reduction of strength in the heat affected zone (HAZ) in the RF‑/ALUMINUM add-on module?
- How do I display some results of all load cases in the printout report, but other results of selected load cases only?
- What is the difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
