Mis-placed anchor rods
Mis-placed anchor rods
(OP)
If anchor rods are mis-placed by inches, can post installed anchors be installed adjacent to the cut off anchors?
My thought is that the cut off anchors would be like a piece of rebar in the footing.
I should say that there is tension on the new post installed anchors.
The cut off anchors would be within the potential failure cone of the new anchors.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

And if the breakout cone cuts through the old anchor it's like added shear reinforcement!
RE: Mis-placed anchor rods
Yes but they wouldn't have the same effect as re-bar would. (If you are thinking about the cut off anchors as providing some sort of reinforcement for the anchor zone.) Depending on the diameter of the bolts, having cut off anchors a few inches away shouldn't have much of an impact on the post-installed anchors. Too close and you could impact the bond......but (say) 1/2" diameter post-installed anchor 2-3 inches away from a cut off 1/2" diameter bolt? It's like the cut off isn't even there.

new 1" post installed anchors 2" away
center to center distances

Given that, I'd take a bit of a reduction. How much would be a judgement call about the amount of failure zone/bond interrupted by the adjacent bolt. sandman21's article provides some good info.

The response did not address my specific situation with an abandoned cast in anchor.
I am waiting on additional information.
