Analysis & Design Software for Aluminium and Lightweight Structures
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.
Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
The following add-on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as stability analyses for aluminium members and sets of members.
RFEM and RSTAB provide various options for form‑finding and design of cable and membrane structures. For example, the RF‑FORM‑FINDING add‑on module can find the shape of cable and membrane structures.
The RF‑CUTTING‑PATTERN add‑on module generates and organizes cutting patterns for 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.
The architectural highlight of the Halle (Saale) bus station include the stylish canopies over the bus platforms. The continuous lights integrated at the roof edges are the real eye-catcher especially at night.
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.
The entrance structure to the dinosaur park Kleinwelka 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.
The removable grandstands are surrounded on three sides by precast seating risers in the north endzone of the Los Angeles Football club soccer stadium. The grandstands are a free-standing system. The system is comprised of aluminum trusses which are demountable from aluminum towers.
A new multi‑purpose hall in the historic city center of Calais in France was inaugurated in mid-June 2015.
The hall made of steel, timber and aluminum has a modular structure. Therefore, it can be used for many occasions (weekly markets, fairs, concerts, spectacles, and many other).
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.
Allianz Arena is a soccer stadium in Munich, Germany, which hosted the opening match of the 2006 FIFA World Cup.
The translucent exterior facade of the stadium emits light in various colors and thus makes the whole arena building very special.

This paper is focused on the specific aspects of designing membrane structures which have specific requirements such as form-finding and cutting patterns generation. These topics are the focus of many research works and there are many methods proposed to achieve the desired results. However, in this paper these issues will be discussed more from the practical point of view than from the theoretical one. The paper will be followed by examples, which will complement the discussed topic and show the special attention required during the design process.
If the check box "Number of load increments" is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently.
The used method is based on a heuristic algorithm.
- How do I determine wind loads on structures of any shape?
- Can I retrace and control the critical buckling value calculated by the internal eigenvalue solver?
- Is it possible to model a semi-rigid composite beam with a line release using members in RFEM?
- Are the effective length coefficients in the add-on modules for the aluminum and steel design automatically determined from the model or do I have to make adjustments?
- How can I get the member end forces to design the connections?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
- I have performed a buckling analysis in RF-ALUMINUM. Where can I find the parameters that the module uses for the design?
