Question:
How do I model a suspended membrane roof structure with line supports?
Answer:
A suspended, linearly supported membrane roof structure can be modeled in RFEM using the RF‑FORM‑FINDING add-on module. For this, define as follows:
1.
Load-bearing structure around the membrane roof
2.
Boundary elements of the membrane consisting of cable elements with the corresponding form-finding settings
3.
Membrane between the boundary elements with the corresponding form-finding settings
4.
Support boundary conditions for transferring the loads
5.
Load case with the "Form-finding" action category to describe the form-finding loads in addition to the prestress
