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.
- What method is applied in the RF‑/DYNAM Pro - Equivalent Loads add-on module?
- It is not possible to enter a nonlinear stress-strain curve. The diagram is initially displayed correctly, but then an error message appears saying that the positive values have to be only entered in ascending order. How can I avoid this message?
- SHAPE‑THIN calculates a very small shear area. Why?
-
My member is oriented at the inclination of principal axis when I import from SHAPE-THIN to a 2D RFEM model. How do I fix this?
- It seems that the members stay not deformed after my RF-FORM-FINDING calculation. What did I wrong?
