beam section local axis l definition (to be stiffeners)

beam section local axis l definition (to be stiffeners)

beam section local axis l definition (to be stiffeners)

I read on the mannual:

By allowing you to specify l, the origin of the local cross-section axis can be placed anywhere on the symmetry line (the local 2-axis). In the above figures a negative value of l implies that the origin of the local cross-section axis is below the lower edge of the bottom flange, which may be needed when constraining a beam stiffener to a shell.

I suppose if I want to bond a I beam by its bottome flange edge to the shell, I should give l=half h (assuming symmetry)as the real local axis location. (Right?)

I did a benchmark to test this(adding a T beam to a shell plate to form a I beam) but the results are not as expected (the deflection, the shear force, the normal stress etc.).

I check the beam orientation, the tie onfiguration, the single beam behavior...don't know what's wrong with it

RE: beam section local axis l definition (to be stiffeners)

Nobody would help?!
