Hi.
In STAAD, major axis is Z-Z and minor is Y-Y. However, in EC3, it's the other way around.
With this, I wish to have confirmation and ask what are the significant parameters to consider about the difference in sign conventions when doing STAAD using EC3?
Using EN1993-1-1:2005, should the parameters LY and LZ axes still be treated as how it is originally defined in STAAD (Z-Z as its major axis)?
When does the axes convention of EC3 should be taken into consideration?
Any guidance is highly appreciated.
Thank you very much.
