Answer:
A suspended, linearly supported membrane roof structure can be modeled in RFEM using the RF‑FORM‑FINDING add-on module. To do this, define:
- Load-bearing structure around the membrane roof
- Boundary elements of the membrane consisting of cable elements with the corresponding form-finding settings
- Membrane between the boundary elements with the corresponding form-finding settings
- Support boundary conditions for transferring the loads
- Load case with the "Form-finding" action category to describe the form-finding loads in addition to the prestress
