This structural plan detail shows the connection of a hollow structural section framing member to a new column with continuity plates matching the beam flange thickness. The hss member connects via a one-inch plate and five-sixteenth fillet welds top and bottom, with five-sixteenth welds on each side. The assembly frames into an existing W21x62 perimeter beam supporting an existing two-and-a-half-inch concrete slab over two-inch eighteen-gauge metal deck with an access floor and Kalwall system above. At the opposite end, the hss member connects to an existing beam using L3x3x3/8 angles on each side with three-sixteenth welds.
