3-Dimensional Open Web Steel Joists
(OP)
Does anyone know where I can find some information on a 3-dimensional open web steel joist system? I've had no luck searching on google.
The bottom chords are off-set from the top chords and the webs connect all the off-set chords - so it's like one big space frame.

Congrats on the PE!
Have you thought about contacting an OWSJ manufacturer to ask them if they have any literature on this. I've called Vulcraft a few times and they've always been extremely helpful.

The only system that I was aware of (and there are probably others) was the Butler Delta System.
Check out thread507-273628: Staggered top and bottom joist chords? in this forum where it is discussed.
Good Luck!!
RE: 3-Dimensional Open Web Steel Joists
I'll call vulcraft tomorrow and I'm going to look at the Butler Delta System now.

The Butler system is your best bet - I think it is a patented system.
