We use standard steel column base plate design per AISC for the baseplate. 3. The anchor bolts should be designed for the T/C loads from the column moment. Usually the slab pours over the baseplate to take out the shear at the base. Also, I would recommend longish anchor bolts with uplift plates on the bottom of the bolts. Off the top of my head, I would guess that a 3/4" x 12" x12" baseplate with 4 - 3/4" diameter x 24" long anchor bolts with 3/8" x 3" x 3" uplift plates on each bolts should be fine for a typical garage. Good luck. Bruce Resnick, SE Parker Resnick Str. Eng.
