Coring Openings in Existing Concrete Panel for Mechanical Ducts
Coring Openings in Existing Concrete Panel for Mechanical Ducts
(OP)
I need to look at coring two holes for mechanical ducts in an existing concrete tilt-up panel. The holes will be 24" and 26" in diameter and will be located towards the top of the panel. The panel is 32' high from finished floor and is 24'-10" wide. I wanted to know if I have to do a full lateral analysis, find the new panel rigidity, and check to see if the cored panel will be adequate to resist the loads, or if there is a faster way to determine whether the openings can be cored? Perhaps a rule of thumb?

We can weigh in more definitively if you post an elevation sketch of the modified panel and a plan sketch of the overall building layout.
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.

Maybe they will stitch-core it...
