Wieland Götzler Add-on Modules STEEL EC3 RF-STEEL EC3

I measure an unbalanced cross-section and receive the warning "Unmeasurable - ER051 moment about axis z at the non-symmetrical cross-section, cuspidor or rod set". Why? What can I do?

Answer

The reason for the warning is that unbalanced cross-sections can not be detected by procedures 6.3.3 EN 1993-1-1 or general procedure 6.3.4 EN 1993-1-1.

You can perform a proof of stability according to theory II. Order as a cross-sectional proof,
which is possible with the additional modules FE-BGDK or STAHL arching torsion.
