About this detail

An open-web steel joist and joist girder connect to a hollow structural section column. A three-quarter-inch thick cap plate is welded to the top of the column and secured with four three-quarter-inch diameter bolts, coordinating gauge with the joist manufacturer. Side connection plates measuring three-quarters by six by nine inches with thirteen-sixteenth-inch diameter holes connect the joist girder to the column, left unwelded to the girder as noted. A wide-flange beam sits above the column supporting a metal roof deck and perimeter continuous angle. An insulated metal panel wall assembly ties into the perimeter with sag rods and wind girts located per framing elevations.
