Hi Steve
You have received a lot of good information so far on the lug. There is another option also. You can weld rebar to the bottom of the base plate or the flange of the embedded column and let the rebar develop the required shear in the footing, grade beam or slab.

Subject: shear lug
Good morning,
Need to resist an unfactored shear force of about 38K at the baseplate level, anchor bolts not an option, thinking about embedding an HSS (say, 8x8x1/2).
Any ideas, suggestions, references for shear lug design?
TIA,
