L · EN 10056-1
L 65×65/6 is an equal-leg steel angle per EN 10056-1: leg length 65 mm, thickness 6 mm, weight 5.9 kg/m, cross-section area 7.5 cm², moment of inertia Iy = 29.2 cm⁴, elastic section modulus Wel,y = 6.2 cm³.
Check to EN 1993-1-1
Enter the design loads and the section is checked for bending, shear and compression with flexural buckling.
Bending and compression are not available for class 4 sections; effective properties per EN 1993-1-5 are required.
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.
For angles the bending values refer to the axes parallel to the legs, which are not principal axes. A moment about one of them also bends the section about the other, so bending has to be resolved into the principal axes u and v and checked biaxially. Buckling already uses the weaker principal axis v.
