Construction Joint in Columns
Construction Joint in Columns
(OP)
Hey y'all, In placing columns (26" and 48" dia) with embedded steel rings w/ studs (See Figure), it's necessary to break the concrete placement into two placements, possibly with as much as an hour between the two. Where would you recommend they break the placement, and why? Would it matter? (Longitudinal steel is continuous)
Thanks for the help!

I'm asking more about if there is any location (A-D) that is preferable over the others to break the pour.

You will introduce a cold joint into the column that may need to transfer some shear. It's almost always a non-issue numerically so no big deal.
I'm pretty sure that I've specified this without considering the formwork. No issues that I'm aware of. Your contractor's lucky to have you on the job.
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.
