When running the steel verfication, you get the error:
Solution
The yielding strength that may be used during the steel verification depends on the dimensions of the cross-section. But the reduction of the yielding strenght can only be done if the dimensions stay under a certain limit (150mm for Belgian annex to EN 1993-1-1).
You can view the limits in the material library (menu Edit > Material library). Select a steel quality and go to the tab page ‘Advanced’.
