Steel Joist bottom chord extension
(OP)
Can one safetly use joist bottom chord extensions to provide adequate lateral bracing requirement for a beam column in a roof or a floor diaphragm? If so what is the magnitude of axial forces to provide the joist manufacturer?
Is there also any code provision that deal with this situation? Which one and where?

I meant Girders in a diaphragm system that see both flexural and axial loads in the analysis.

OLD rule of thumb says you need 2% of the column axial load to brace it?? So use 5% and you should be good to go.
