This doctoral thesis by Rostislav Lang deals with the design and analysis of membrane structures using FEA software.
Add-on Modules - Tensile Membrane Structures
The RF-FORM-FINDING add‑on module searches for shapes of structures subjected to tension or stress, such as membrane and cable structures, shells, and other structures.
The shape is calculated by the equilibrium between the surface stress (prestress) and natural or geometric boundary conditions.
RF-CUTTING-PATTERN calculates and organizes the cutting pattern for membrane structures.
The planarization process is carried out in compliance with the minimum energy theory.
It offers the option to couple surfaces with the stiffness types „Membrane" and „Membrane-Orthotropic" with the material models „Isotropic nonlinear elastic 2D/3D" and „Isotropic plastic 2D/3D" (RF-MAT-NL add-on module required). This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
The engineering company ACS provided the full project structural analysis and design, including the fabric membrane and frame structure.
The Belin-Béliet (department of Gironde) municipality tennis club, founded in 1976, completed a new tennis hall in July 2019. This project was made possible due to a subsidy provided by the French Tennis Federation along with the support of the municipality.
Every summer, movie nights and other events take place on the banks of the Elbe in Dresden. Over 200,000 visitors throughout the summer attend more than 55 films and concerts, complete with national and international artists.
For twenty years, the Circus Festival in Latina has been thrilling audiences with the world’s most talented artists. The International Circus Festival of Italy, founded by Giulio Montico and operated by the Montico family, has been recognized globally since the first performance. The circus tent built in Latina has made it possible to appreciate the quality of the many artists performing there.
The Under Canvas company provides a unique opportunity for all-inclusive adventure glamping (glamorous camping). Established in 2009, the company has grown to include multiple luxury glamping resorts and customized events all over the country.
Under Canvas began in 2009 with the opening of an all-inclusive glamping adventure package. It has since grown to include eight luxury glamping resorts and a customized event offering, bringing the glamping experience to life everywhere in the country.
The architectural highlight of the Halle (Saale) bus station includes stylish canopies over the bus platforms. The continuous lights integrated at the roof edges are a 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 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.
A unique project called "Oxigeno" is currently under construction in San Francisco de Heredia, San José, Costa Rica. The recreational and commercial space, which measures almost 1,345,489 ft², offers the visitor a relaxing shopping atmosphere in harmony with nature.
A unique structure which roofs the main bus station in the Swiss town of Aarau was built at the end of 2013.
The canopy has a cloud-like shape and contains the largest single-chamber cushion in the world. It has a volume of 63,920 ft3 and a roofed area of 11,517 ft2.
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.
The Eden Project is a complex of two biomes and outdoor gardens with plants from many diverse climates and environments.
The biome is a steel frame structure with cladding panels consisting of triple-layered membrane cushions made of ETFE foil.

Doctoral Thesis on Membrane Structure Design According to FEA
- How do I determine wind loads on structures of any shape?
How do I activate the RF-FORM-FINDING add-on module?
- Is it also possible to calculate cable structures in RFEM and RSTAB?
- Although I have modeled two identical structural systems, I obtain a different shape. Why?
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- It seems that the members stay not deformed after my RF-FORM-FINDING calculation. What did I wrong?
Can I export my cutting pattern?
- How do I model a tent roof with two cone tips?
- How do I model a suspended membrane roof structure with line supports?
