Stress Analysis Software
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.
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.
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.
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.
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.
This four-story building, made of 56,700 ft3 of CLT and 1,200 ft3 of glulam material, serves the lodging needs of the Redstone Arsenal Army post.
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.
Most Common Performance Classes L1 and L2 with Corresponding Basic Values of the Axial Post-Cracking Tensile Strength
Stress-Strain Curve in the Tension Area According to  to Determine Internal Forces and Deformations in Nonlinear Methods
Stress-Strain Curve on the Tension Side According to  for Cross-Section Design in the Ultimate Limit State
Stress-Strain Diagram According to  for the Compression Zone: a) for the Nonlinear Calculation; b) for the Cross-Section Design
- 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?
- 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 by 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 the selected load cases only?
- What is the difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
- Where can I find the determined support forces for the crane runway girder? At the bottom flange of the crane runway girder or in the shear center of the cross-section?
- For cross-section design of a flat steel, I obtain abnormally high shear stresses due to the torsion in the STEEL EC3 add-on module, which can be disproved by a simple manual calculation. What is the error?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
