This connection utilizes two 5/8-inch thick ASTM A572 Grade 50 steel gusset plates welded to a wide flange column to support diagonal hollow structural section braces. The upper brace is secured to its gusset plate with four 3/4-inch diameter A325N bolts, while the lower brace is secured with six 3/4-inch diameter A325N bolts. Fillet welds of 3/16-inch and 1/4-inch size are specified for the gusset plate attachments, with specific spacing and edge clearances noted. A horizontal hollow structural section beam frames into the column web using a separate connection plate, with the column flange cut for clarity in the drawing. All brace connections maintain a minimum 1/2-inch clearance from the gusset plate edges.
