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.
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 the wind load on the model areas?
- 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?
-
Can I export my cutting pattern?
- How do I model a suspended membrane roof structure with line supports?
- How do I model a tent roof with two cone tips?
- I would like to calculate and design "temporary structures." What do I need for this?
- I have already divided my membrane roof into individual surfaces. Can I quickly create a cutting pattern from these surfaces?
