Epoxy Anchors at Cold Joint
Epoxy Anchors at Cold Joint
(OP)
I have an existing spread footing I am adding on to and placing a pier above. Field observations have shown that, contrary to the original design drawings, the edge of the existing footing is inline with the epoxy anchor placement.
My question is, is it okay to proceed with epoxy install at this cold joint or would it be better practice to chip the existing foundation back a few inches and epoxy into the new footing expansion? The anchor rod location can not be moved due to project constraints. Attached a sketch

Is this a gravity column? Part of a moment resisting frame? Part of a braced frame?

Do you have a net uplift?
Horizontal shear parallel with the joint?
Horizontal shear perpendicular to the joint?
Gravity loads?
What are the rough magnitudes of the forces?

As an alternative:
I suspect that you could develop 10k of tensile force in the two anchors that do not fall on the joint.
I suspect that you could develop 10k of capacity in just the top "cap" and another 10k of capacity between the cap and the "lower" footings.
