How are riggings processed in RF‑FORM‑FINDING, concerning the prestress load to be applied. Is it necessary to assign a prestressing force to the riggings?


For form-finding, it is primarily important to apply the prestress for the membrane and the border cables that are possibly available. It is not necessary to prestress the riggings.

The riggings can be created as a tension member with its initial length (see the figure). Due to the prestressed membrane and the border cables, the load for the rigging results during the calculation.
