Lateral-Torsional Buckling Capacity of Cantilever I-Beams

Lateral-Torsional Buckling Capacity of Cantilever I-Beams.
I'm lost.. where can I find this capacity? I've found some papers about LTB on cantilever beams but they look so scientific for the problem I'm solving.
Where Can I Find?

Start with Steel Interchange March 2005, this isn't quite current but will get you started.

This here is a pretty straight forward guide:

https://www.steelconstruction.info/images/9/99/AD-408.pdf[/URL]]AD 408: Effective length of cantilevers

Use the effective length in your calculation as give an design it as per your normal code requirements of a beam under bending. You'll notice that under the wrong conditions a cantilever can have an effective length of 7.5L! Put some better twist restraint in there at the supports and you can vastly improve this.
