A hollow structural section brace connects to the underside of a structural steel beam via a gusset plate measuring 1 foot 6 inches by 6 inches by 1/2 inch in Grade 50 steel. The gusset plate features an 8-inch dimension along the beam flange and a radius cut on its outer edge. The hollow structural section beam is taper cut to maintain a 1-inch clearance to the bottom of the supporting beam, intersecting at a work point with the brace centerline. A 1/4-inch fillet weld with a 6-inch length secures the connection, and a note indicates a design preference for the taper cut with a request for erector advice.
