Known limitations for RFEM/RSTAB

This article is also available in:

For now, the link works for a wide variety of connections/joints. However, please take into account yet unsupported functionality.

Limitation: RFEM/RSTAB BIM link provides only the export of connections and members under the Eurocode (EN).

Workaround:  N/A, other codes will be introduced in future versions of IDEA StatiCa.

Limitation: Exporting of multiple selections of nodes and/or members from RFEM/RSTAB to IDEA StatiCa doesn't work.

Workaround: N/A, only single selection of a single node and corresponding member or a single member is allowed for export on the side of RFEM/RSTAB.

Limitation: Export of a node when the display setting "Sets of member" is turned ON may lead to incorrect data transfer for some member cross-sections and import of extra members or an error message.

Workaround: Turn the "Sets of member" OFF and repeat the export of the node.

Limitation: Geometrical eccentricity – joint node is not in the central point.

Workaround: RFEM/RSTAB offers more ways of input of eccentricities. The eccentricity input using the Local x,y,z coordinates causes difficulties in transforming the data to IDEA StatiCa due to the variety of coordinate system options in RFEM/RSTAB. In case, please use the Global X,Y,Z coordinates eccentricity input instead.

Limitation: Exporting a beam with a haunched end or another type of conical or other shaped beam ends is not possible.

Workaround:  The haunch is neglected and can be modeled afterward in IDEA StatiCa
