Hi Noy:
Are you referring to a process that a threaded insert could provide? A threaded insert could be threaded to a hooked bar in the wall/column and then after the wall is poured, a beam re-bar could be threaded into the same insert. I would design a corbel to hold the vertical reaction of the beam in the second pour as well.
We have done this successfully on several projects.
If you are re-bending an embedded rebar, the second bend after the first pour would severely weaken the rebar.
Respectfully,

Subject: pull-out bars
Is there provision in ACI or any standard/code that allows 'pull-out bars'? i am refering to a reinforcing bar that is bent and embedded in concrete wall/column, and then pull it out to connect/splice the reinforcing bar of a beam or slab. (personally, i do not agree with this approach but some engineering firms allow it) please give me insight. thanks.
