Lateral buckling for cantiliver?

It is possible to calculate lateral buckling for steel I/H beam supported from both sides. What about cantiliver?

For precise calculation I need to pick the right load type (actually representing bending moment curve shape), but in robot all load types are given for supported bars from both sides. As I know there are no regulations in EC for such (cantiliver) types of bars, but such regulations exist in NCCI: elastic critical moment of cantilicvers. SN006a-EN-EU.

I have added this request to the wish list.

 

Mind that you can enter value of Mcr manually in the member type label and you may find this option helpful for cantilevers.

One more question: trying to calculate lateral buckling for L section (in my example L100x100x10) and get message from Robot, that "for bars 1 the program has not performed the lateral buckling verification. Bars were assigned such section type for which the program does not perform the lateral buckling analysis or the lateral buckling verification is not required (for example My=0 - no bending)".

??? Any comments? Section type is L, not tube, so i should perform lateral buckling for this. I also have a bending moment...

I may be wrong but I think that the EC3 code doesn't  describe the way of checking LTB for angles?
