Specific Requirements of Membrane Structures
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.

Nonlinear Material Law for Membranes
In RFEM, there is an 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.
Frequently Asked Questions (FAQ)
- Is it possible to also design membrane structures in RFEM?
- Is it possible to analyze the effects of an hermetically sealed object with RFEM?
- How do I activate form-finding of a membrane surface?
- How do I create models of neighboring buildings for a numerical flow simulation in RWIND Simulation?
- How can I influence the sag of the found shape in RF‑FORM‑FINDING?
- I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?
- As part of my bachelor thesis, I would like to integrate the RSTAB printout report into LaTeX. There, you can completely integrate a PDF document as shown in the viewer. This also works with any PDF document, but not with the printout report created by RSTAB. What could be the reason?
- How can I set the deformation coefficient kdef in the program?
- Does the program use different values of modulus of elasticity for different temperatures? How to activate it?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
