Unusual steel joist

Recommended Posts

I've ran across a manufactured joist that I've never seen before and it has me slightly confused.

I've tried to back out an allowable loading using both A7 and A36 steel as this transition occurred while poured gypcrete roofing was being used, however, neither steel designation gives me anything close to what I anticipate the design loading should be. I've checked and double checked the section properties and the chord shapes appear to be formed from one piece. I've incorporated a sketch for reference.

If you've seen anything like this before, please tell me what you can about it. Preferably, I'd like to know the manufacturer of joists of this type. I suspect the structure was built in the early 60's in the Atlanta area.
