Base Plates at Columns with Brace Gussett Plates
Base Plates at Columns with Brace Gussett Plates
(OP)
Just curious what everyone elses does when it come to a brace at the base of a column. Do you weld the gusset to the col and bp or just the column? do you center the bolt pattern in both directions on the column? do you shift the anchor rods and account for the eccentricity?
just looking for some ideas to retool what we've been doing.

If you are designing/detailing for seismic, be sure to set your brace back far enough from the ends of the gusset plate welds to allow inelastic out-of-plane buckling in the gusset without tearing at the column/plate welds. See the AISC Seismic Commentary for a good detail of this.

As JAE said, when you make the workpoint the bottom of the base plate you will usually need to connect to the plate and the column. Often you'll see inexperienced detailers keep the workpoint in the correct location but then try to get approval on a connection arrangement which eccentrically loads into the column only. Stay away from those!
