I get the message 'Torsion on cross-section class 4'. Why does this appear and what can I do?

Answer

Torsion at cross-section class 4 is not regulated in Eurocode 3, which is why this warning appears.

You can change the cross-section, classify the cross-section in Window 1.3 manually to Cross-Section Class 3, or neglect the torsion in the 'Details' dialog box, 'Ultimate Limit State' tab at your discretion and on your own responsibility.
