A gusset plate connects into a slotted hollow structural section member, which is sized per detail along with the shape and thickness of the gusset plate. The slot width equals the gusset plate thickness plus one-sixteenth of an inch and is centered on the member, featuring a drilled hole diameter matching the slot width and a one-inch maximum slot length. Fillet welds join the gusset plate to the hollow structural section, with weld sizes specified in a table based on the hollow structural section wall thickness.
