Specific Requirements of Membrane Structures
This paper is focused on the specific aspects of designing membrane structures that have specific requirements, such as form-finding and cutting pattern generation. These topics are the focus of many research works, and many methods have been proposed to achieve the desired results. However, in this paper these issues will be discussed more from a practical than a theoretical point of view. The paper will be followed by examples that will complement the topic under discussion and show the special attention required during the design process.
Display of Topology on Deformed Structure
With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
- I cannot define the prestress separately for warp and weft in RF‑FORM‑FINDING. How can I activate it?
- Is it possible to export the form-finding results? For example, in a DXF file?
- How does RWIND Simulation determine the pressure due to wind load on model surfaces?
- Which mesh size should be set for a numerical wind flow analysis?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- 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?
- I want to create a mapped mesh for a circular hole plate. Is it possible to generate such a mesh in RFEM?
- It seems that the members stay not deformed after my RF‑FORM‑FINDING calculation. What did I wrong?
