Historic rebar identification
(OP)
I have a concrete slab that is reinforced with what appears to be 3 wires twisted together, about 3/16" dia wire.
The slab is about 6" thick with the twisted bars bottom at 6" on center spanning 9 feet between dropped concrete beams. It was a 4 story warehouse buildng, not sure of the age but obviously old, and it's in the midwest.
Any info on this type of reinforcing would be appreciated.

You might try to figure some kind of cross sectional area and then run some designs - just be very conservative.
