Embed Plate with Welded Rebar or DBA's 1

[slickdeals]

My understanding is that the use of a welded rebar or a Nelson DBA in an embed plate gets us out of the ACI 318 Appendix D mess. This was based on the failure modes of anchors not applicable to deformed bars. A reinforcement bar fully developed in concrete can carry it's tension load capacity as long as adequate cover is provided. Assume that cover is say 3", the code will let me develop full tension capacity of the reinforcement.

I was reviewing the ICC-ESR for Nelson DBA's and they seem to have much tighter restrictions for edge distance and spacing.

Has anyone used the values in these tables or assumed that the full tension capacity of an embedded deformed bar can be achieved?

When I look at the picture, I don't see epoxy on the bar beyond the breakout cone so of course the short breakout occurs. I want to see the picture where the epoxy goes the full depth (or at least one where the bar doesn't look so clean). I suspect the breakout cone in that scenario looks closer to what AppD says.
