How to deal with lateral buckling parameters?  Which is the recommended way to deal with it in robot?

In the example structure beams 5, 6, 18, 19 fails for buckling.  These beams were modeled as one beam from column to column.  But other beams are connected to them so these beams are restrained why does the robot does not take that into account automatically and take into account the correct lateral buckling length. Buckling parameters used Lcr = Lo.   Is there a setting that takes that into account automatically?

Beams that modeled from node to node like 7-11 do not fail in design

Thank you

Use "consider adjoining bars automaticaly" or something like that in intermediate restraints window.

can you be more specific pls?

thank you

Try to group bars into 'real' beams. Try to think how would you design them manually; determine where they are supported to decide how to divide or 'merge' elements defined in the model so that they stand for the 'real' beams from the 'structural' point of view.
