Question

I am getting 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.
