Stability Analysis Software
The structural analysis software RFEM 6 is the basis of a modular program family. The RFEM main program 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 analysis software RSTAB 9 has a similar range of 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.
The Structural Stability add-on for RFEM 6 / RSTAB 9 calculates critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, it is suitable for the linear and nonlinear analysis of the structural stability behavior.
The Torsional Warping (7 DOF) add-on for RFEM 6 / RSTAB 9 allows you to consider the cross-section warping as an additional degree of freedom when calculating members in RFEM and RSTAB.
The RF‑IMP/RSIMP add-on module for RFEM 5 / RSTAB 8 is used to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model.
The PLATE‑BUCKLING stand-alone program or the RF‑/PLATE‑BUCKLING add-on module for RFEM 5 / RSTAB 8 allow for buckling safety design of rectangular plates according to the standard EN 1993‑1‑5.
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.
The entrance structure to Kleinwelka Dinosaur Park near Bautzen, Germany has a total height of 72 ft and resembles mitosis. Mitosis is a type of cell division and the origin of life. The bionic structure consists of 1,389 steel tube members assembled together at 269 joints.
An impressive roof structure was constructed over the Passion Play open-air theater in Sömmersdorf, Franconia (Germany). The self-supporting spatial steel structure includes a PVC membrane roof covering the 14,908 ft² auditorium. Only four foundations in total support the entire roof structure.
With an area of 110,000 ft², the North Surrey Sports and Ice Complex includes three ice rinks, event rooms, and restaurants, as well as outdoor areas. StructureCraft, a customer of Dlubal Software, was selected as the structural engineer and builder of the roof structure...
One of the most modern power stations for energy production, based on renewable resources, can be found in Schwendi, Southern Germany. Following the design of the Milan architect Matteo Thun, an architecturally sophisticated framework consisting of reinforced concrete, steel, and timber has been created.
The construction of a building with a spectacular facade was completed in the German town of Schwäbisch Gmünd for the 2014 State Garden Show (Landesgartenschau).
The project of the local association for noble metals is supposed to emphasize the reputation of the "gold and silver" town.
The path leading through forest treetops in the Bavarian Forest National Park in Germany has a total length of 4,265 ft and is the longest treetop walk worldwide.
The treetop walkway leads to the spiral structure of the egg‑shaped tree tower with a height of 144.3 ft.
The company BAUER Maschinen GmbH, working in the field of specialist foundation engineering, has developed a new deep drilling rig.
The system is used to make borings reaching to a depth of 22,965 ft in the area of geothermal energy, oil, or gas.
The first treetop walkway in the Czech Republic opened in Lipno in 2012. The path is 2,214.5 ft long and leads to a tree tower.
On the top platform, at a height of 131 ft, visitors can enjoy the wonderful view from the wooden lookout over Šumava National Park and Lipno Dam on the Vltava River.
The "Centre Pompidou-Metz" arts and cultural center in France is a branch of the "Centre Georges Pompidou" museum in Paris, one of the most significant museums worldwide.
The building design represents an oversized Chinese straw hat and the girders symbolize the straw braided in three directions.

In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5.
The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
- Which formula is used for the calculation of the elastic torsional buckling force for torsional buckling Ncr,T in RF‑/STEEL EC3?
- What is the purpose of the "Calculate eigenvector for unstable model..." option in RF‑STABILITY?
- In RF‑/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- How can I perform a stability analysis or walls in RF‑CONCRETE Surfaces?
- What is the critical load factor and how is it possible to determine it?
