About this detail

A structural steel beam connects to the top of a hollow structural section column with a three-quarter-inch-diameter erection bolt and five-sixteenth-inch fillet welds. A one-quarter-inch stiffener plate measuring one-half the beam depth minimum is provided on each side where no intersecting beam occurs, welded with one-quarter-inch fillet welds. A shear plate extends for intersecting beams to the bottom flange on each side, with a maximum one-half-inch gap maintained at the column top. The plate measures three-eighths of an inch thick by the hollow structural section width plus one inch wide, centered on each side of the hollow structural section.
