About this detail

A hollow structural section column supports a joist girder topped with a three-quarter-inch thick cap plate and two erection bolts. A metal roof deck bears across the top chord with typical welds left unassigned to the girder per plan. The joist seats utilize five-sixteenth by three-inch by one-foot four-inch plates on near and far sides, secured with three-sixteenth-inch fillet welds typically on each side. A one-half-inch plate with a thirteen-sixteenth-inch diameter erection hole connects the joist girder. For roof slopes less than one inch per foot, the cap plate is sloped; otherwise, the girder seats are sloped.
