Problem with L-profiles (CAE/CAEP or VL and VLP)

[andreas.r.ekholm]

Hi!
I have trouble to get a working model for truss beams. We use L-profiles (CAE/CAEP) for top and bottom cords and want to check the utilization with Euro-code (stability check).
Here is where we get trouble. L-profiles has four directions that has to be checked and CAE and CAEP does only have two directions in Robot. Please read moore in my attached file.

Mr Andreas,
i see that you use double L for the chords of the truss. Maybe, if the requirements are met by the EC3, you can treat them as a single monosymmetric section (double equal angles connected back to back) and then check for buckling. You probably avoid all that trouble with the axis directions.
