Column Ties
Column Ties
(OP)
I am reviewing a shop drawing where the detailer has shown the lateral ties for a square column as four individual pieces of rebar per tie (one bar on each side of the square tie). Each piece has a hook on each end and all of the reinforcement is enclosed by the ties.
This arrangement looked a little unusual to me. Does anyone know of any concerns or ACI requirements that would prohibit this arrangement?

I would think that the GC would not be very happy about this situation.
I would require the perimeter tie to be continuous.
RE: Column Ties
We have used this kind of tie for interior bars with columns of 8 or 12 bars (with > 6" clear space between bars) where one end hook is a "J" hook and the other end a standard 90 degree hook. The thought is that we try to get as much hook as we can by using the J and this allows installation by hooking the J around the long. bar and then rotating the 90 deg. hook onto the other bar.
