Tips & Tricks
During the form‑finding process, the elasticity of a substructure is also taken into account when searching for the equilibrium state. You can also consider large deflections of supporting trusses or pure bending deformation of the edge beams when determining the membrane shape.
If no additional deflection of membrane supports appears, the respective edges can be defined with a support including the nonlinearity of “Form‑finding stage only.” Thus, these supports are effective in the form‑finding process only. In this step, all relevant points and lines are supported in the selected direction. These settings do not apply to any further calculations using the new membrane shape.
