RE: Anybody knows this old concrete designation

Does it have anything to do with the old standard rebar bend designations?

http://www.anchsand.com/Portals/3/StandardrebarBen...

I.e., End-Middle-End of bar configured with the End portion of Type 3 - Middle portion of Type 1 - Middle portion of Type 100.

Just a guess at this point...I'll probably have a good laugh when someone explains what it actually means.

Agree that T & B = top & bottom.

What is the reinforcing for? Slab? Beam? Wall?
