Stability Analysis Software
Are you still looking for a convenient structural analysis program? Then you are right here! RFEM 6 is the basis of a modular program family. In the main program RFEM, you can define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Here you can also create combined structures as well as to model solid and contact elements. Read more about RFEM 6 here:
It becomes more special with the spatial frame & truss analysis program RSTAB 9. The range of functions of the RSTAB product range is similar to that of the FEA software RFEM. However, due to the special attention to beam, frame, and truss structure, it is very easy to use. It is not for nothing that for many years, RSTAB has been the best choice for structural analysis and design of pure structural member models.
The Structure Stability add-on for RFEM 6 / RSTAB 9 is a true multi-talent. It calculates critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, it is suitable for linear and nonlinear analysis of structural stability behavior.
What sounds complicated doesn't always have to be complicated. At least not with the right program by your side. The Warping Torsion add-on (7 degrees of freedom) for RFEM 6/RSTAB 9 allows you to consider cross-section warping as an additional degree of freedom when calculating members in RFEM and RSTAB.

There are numerous helpful add-on modules for RFEM 5 / RSTAB 8. For example, RF‑IMP/RSIMP for RFEM 5 / RSTAB 8 is used to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model. Discover innovative possibilities in structural engineering with Dlubal Software.
In addition to the main Dlubal programs with their add-ons, there are also stand-alone programs available for you. The PLATE-BUCKLING stand-alone program is one of them, and performs plate buckling analysis of rectangular plates according to the standard EN 1993‑1‑5. The same range of functions is included in the RF‑/PLATE‑BUCKLING add-on module for RFEM 5 / RSTAB 8.
The Dlubal structural analysis software also enables you to work together. 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) to read or write the data from or 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 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 1,300 m 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 44 m.
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.
