It's kindda tequenical question. I analyse some steel structure using EN 3 (Eurocode) code with ASTM properties (W-shape)
One of company made a comment about that.
I reckon there isn't any problem with "diff code with diff prop.". Only concerning points would be 'area', 'Ix', 'Iz' this kindda stuff.
Should I select Euro. properties such as IPE when using EN 3 code to get exact and proper results?
