Does anyone know of applicable codes or standards for the structural design of welded TKY connections in aluminum trusses with hollow circular or box members?

D1.1 contains extensive guidance on the structural design of *steel* TKY connections with round and box members.

However, D1.2 contains zero guidance on designing *aluminum* TKY connections with round and box members.

D1.2 refers to the Aluminum Design Manual for design of welded connections; the ADM also has zero guidance on the subject.

I've searched the web 'til I'm cross-eyed and can't find any industry standards on the subject. 

Does anyone have experience with this?
Does anyone know if future updates to D1.2 will include such guidance?

Thank you!
