In RF‑CONCRETE Members, I receive the error message: "Set of members No. will be removed from the calculation." What does it mean?


The sets of members to be designed in the add-on module must be based on the same or the consistently running cross-section.

An exception is a set of members consisting of ribs. This only results in an identical cross-section if the integration width of the rib is selected to be the same. Thus, there must be a single rib type for the entire set of members.

Tapered sets of members are only designed if the entire set of members has a linear cross-section diagram.
