Answer:
During the development of the FRAME‑JOINT Pro add-on module, the bottom end plate extension was introduced, as it improves the load transfer of the compression force into the column.
It is not possible to deactivate the extension, and the minimum dimension of it is defined as follows:
uu = max
- End plate thickness
- √2 * bottom flange weld
- For end plate height < 200 mm → min 10 mm
- For end plate height > 200 < 400 mm → min 20 mm
- For end plate height > 400 → min 30 mm
