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.
RF-STABILITY/RSBUCK determines buckling modes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behaviour.
RF-IMP/RSIMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.
RF‑/STEEL Warping Torsion is an extension of the RF‑/STEEL EC3 add‑on module. It performs torsional‑flexural and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.
The PLATE-BUCKLING stand-alone program or RF-/PLATE-BUCKLING add-on module performs plate buckling analysis of rectangular plates according to the standard EN 1993-1-5.
A single-family home with a remarkable roof structure stands in Upper Austria since 2014.
The circle in the center of the building is spanned by a tented roof built as a visible wooden structure. Together with the light‑flooded glass facade, it is a real eye‑catcher.
The construction of a building with a spectacular façade 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 first Czech treetop walk was opened in Lipno, Czech Republic, in 2012. A path is 675 m long and leads to a tree tower.
The timber look-out tower with a height of 40 m provides wonderful view over the Šumava National Park and the Lipno Dam on the Vltava River.
The company BAUER Maschinen GmbH, working in the field of specialist foundation engineering, has developed a new deep drilling rig.
The steel drilling structure with a height of 42 m is used to make borings up to a depth of 7,000 m in the area of geothermal energy, oil or gas.
G3 Shopping Resort is the largest construction project for cross-laminated timber in Europe.
The structure with architecturally sophisticated design consists of cross-laminated timber slabs and glued-laminated beams. Both architectural and structural highlight is the huge timber roof spanning the building like a giant wave.
The path leading through forest tree-tops in the Bavarian Forest National Park in Germany has a total length of 1,300 m and is the longest tree‑top walk worldwide.
The tree-top walkway leads to the spiral structure of the egg‑shaped tree tower with a height of 44 m.
The arts and cultural center "Centre Pompidou-Metz" in France is a branch of the museum "Centre Georges Pompidou" in Paris, one of the most significant museums worldwide.
The building design represents an oversized Chinese straw hat and the girders are symbolizing the straw plaited in three directions.
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.
When performing the stability analysis of members according to the equivalent member method, considering internal forces according to the linear static analysis, it is very important to determine the governing equivalent member lengths.
Basically, you can design structural components made of cross-laminated timber in the RF-LAMINATE add-on module. Since the design is a pure elastic stress analysis, it is necessary to additionally consider the stability issues (flexural buckling and lateral-torsional buckling).
