    Eurocode 3 - Combined bending and compression, lateral buckling reduction factor not applied to Mz

    Again thank you so much KootK. There are indeed diagonal braces connecting the 4 main chords and taking care of transfering shear. I'll keep following that method for rectangular sections but at least I feel better about Ix=Iy sections. I'll just make sure torsion is not significant.

    Eurocode 3 - Combined bending and compression, lateral buckling reduction factor not applied to Mz

    Thank you both, @KootK , Makes sense. Do you think that also applies to square box trusses? That's a kind of section I often work with, and when I can't model the whole truss in 3D I calculate the moment of inertia of the truss based on the 4 chords, and in that case Ix=Iy. I seem to remember...

    Eurocode 3 - Combined bending and compression, lateral buckling reduction factor not applied to Mz

    Thank you so much KootK, I really like your explanation, this now makes sense to me when I think about I beams or rectangular hollow sections. I was going to ask about square and circular hollow sections but I just remembered that Eurocode 3 says that those sections are not susceptible to...

    Eurocode 3 - Combined bending and compression, lateral buckling reduction factor not applied to Mz

    Hello dear colleagues, After many years browsing this great forum to find useful answers, I have finally created an account to ask my first question which I've had for a while but couldn't find answers to. In the Eurocode 3 for steel, when looking at combined bending and compression in section...
