I have to design a footing in an existing building for a new steel column which is located right next to an existing exterior CMU wall footing. In other words, the column would be sitting on the edge of the footing. I would appreciate tips on how to go about it (Shear considerations, etc.) ACI Code. I am only considering gravity loads as it is a low seismic area.

Don't forget to check against punching shear action...

1. Place new footing immediately below existing strip footing, then place drypack grout between new and existing footings. If necessary, do in stages to avoid undermining too much of the existing footing.

2. Abut new footing to existing strip footing using drilled dowels into existing concrete. Strap new footing to another interior footing if necessary and if practical.

How far below finished floor is the top of the existing footing? Would conditions be suitable for helical or micro piles?

It usually takes quite a bit of footing self weight to make edge loaded footings work without employing some kind of strap/rectifying beam.

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.
