check for weaker axis in EC3?

[andreas.r.ekholm]

Hi
im trying to create a truss model that consists of two L-profiles (CAE) in the top and bottom chords. When i run the EC3 calculations i get a warning that "angle is not checked for buckling relative to the weaker axis of the main system". Further investigations when checking in to the calc.notes of the L-profile shows ony calculations of x and y axis. The L-profile has two more axis that needs to be checked?! Is this a limitation i Robot or is there no such check in EC3?. I hope that someone can look in to this problem and help us. Thanks /Andreas Ekholm

Andreas,
I think you have to use CAEP type profiles.
CAEP axis are principal axis.
