Dlubal RFEM 5 - Add-on Modules: RF-FORM-FINDING & RF-CUTTING-PATTERN
First Steps with RFEM
Add-on modules for form-finding of membrane and cable structures. The shape is calculated by the equilibrium between the surface stress (prestress) and natural or geometric boundary conditions.
- Simulation of isotropic and orthotropic membranes
- Consideration of the substructure flexibility
- NURBS transformation
- Generation of additional NURBS points for load input

Cable and tensile membrane structures are regarded as very slender and aesthetic building constructions. The partly very complex double-curved shapes can be found using suitable form-finding algorithms. One possible solution is to search for the form via the equilibrium between the surface stress (provided prestress and an additional load such as self-weight, pressure, and so on) and the given boundary conditions.
