Slab Schedule "Bottom Bars Bend Up"

Slab Schedule "Bottom Bars Bend Up"

Slab Schedule "Bottom Bars Bend Up"

(OP)
I am evaluating a concrete floor in a building constructed around 1952. A snip of the slab schedule is attached. It indicates "Bottom Bars" at say #4@10" then the next column says "Bend Up" and what looks like 1/2? Does anybody know what that means? There are no sections that show the rebar.

RE: Slab Schedule "Bottom Bars Bend Up"

I think it means that half the bottom bars are bent up into the top layer, as was the custom at the time. Labor was cheap, material was expensive, so they "trussed" the bars to where the moment demand dictated.

Interesting, thanks hokie66. Found this link:

Without details, I don't think I would count on it, but that leads me to believe that there may have been some fixity expected at the ends and the slab may be able to take more load that a simply supported beam analysis. Would you agree with that?

RE: Slab Schedule "Bottom Bars Bend Up"

No, I would not agree or count on fixity at the simply supported ends.
