Enter the design loads and the section is checked for bending, shear and compression with flexural buckling.

Bending/ 137.4 kN·m

Shear/ 546.5 kN

Compression/ —

The compression check is not available: in uniform compression the section is class 4 and effective properties per EN 1993-1-5 are required. Bending and shear are unaffected.

Yield strength is taken from the product standard for the governing thickness, so above 16 mm it is lower than the nominal grade. Simplified checks per EN 1993-1-1, without M+N+V interaction, without lateral-torsional buckling and without web shear buckling. Verify with a full design.
