This structural steel connection details a heavy braced frame gusset plate assembly at a column and beam intersection. The web plate connects using twelve one-and-one-quarter-inch-diameter Group B slip-critical bolts with Class B faying surfaces, utilizing oversized holes in the plate and standard holes in the wide flange. Stiffener plates are welded with five-sixteenth-inch fillet welds typical at the flange plate, while built-up wide flange webs receive three-quarter-inch fillet welds. Wide flange fin and stiffener plates are detailed to bear per AISC guidelines. Diagonal braces frame into the gusset plate assembly with bolted splice connections.
