An HSS beam connects to a wide-flange column flange and web using L4x4x1/2 structural angles welded top and bottom. The connection to the column flange utilizes top and bottom angles sized to the column width minus 1-1/2 inches, welded with 5/16-inch fillet welds on both sides. The connection to the column web uses angles sized to the column depth minus 2-1/2 times k. The HSS beam maintains a maximum clearance of 1/2 inch from the column face, with 1/4-inch and 5/16-inch fillet welds applied to secure the angles to the beam walls.
