Answer:
The reason is due less to the defined cross-section than to the material properties. There are yield strengths and limit stresses, depending on the component thickness. A non-designable situation results when the thickness of a cross-section part is greater than the existing thickness range.
To fix this, you have the following options:
- You can create another thickness range with the corresponding stresses within the add-on module in Window 1.2 "Materials".
- Alternativ können Sie in der Bibliothek von RSTAB/RFEM ein anderes Material mit geeigneten Dickenbereichen wählen
