A steel beam featuring flange width Bf and flange thickness Tf connects to hollow structural section columns sized per plan. The connection uses base plates or cap plates secured with three-quarter-inch diameter bolts, with plate thickness matching flange thickness Tf or one-half inch minimum. Three-eighths-inch stiffener plates are provided where columns occur above or omitted depending on location, welded with typical one-quarter-inch fillet welds.
