Pullout Capacity of Embed plate in bottom of DT Stem
Pullout Capacity of Embed plate in bottom of DT Stem
(OP)
I have an embed plate in the bottom of a existing double tee stem(10DT24). The embed has a couple of 12-inch long #3 D.A.B extending up into the stem. I can't find a method anywhere that says how to calculate the tension capacity. I could look at the concrete breakout failure mode per App D, but I am not 100% sure what the Hef would be. My initial thought is something less than the full 12" length, but App D tells you to use the full embed for an epoxy bar so it doesn't seem unreasonable to use the full 12".
How do others address this?

I have no idea who manufactured them, but the bar itself isn't my problem. It is the edge distance issues with the bars installed vertically in the bottom of the stem. What is the breakout shape? You can't just breakout the concrete with a few strand passing through, but the pre-compression from the strand would help flatten out the 1.5:1 App D failure surface.

In other words, if I develop a piece of rebar, I dont have to use AP. D right?

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
