About this detail

Standard framing conditions for steel joists and girders bearing on structural steel columns consist of steel joists, steel girders, wide-flange steel columns, and metal roof decking. Connections feature two-bolt or four-bolt arrangements using half-inch or three-quarter-inch diameter A325 erection bolts, specific fillet weld sizes, and three-eighths-inch by six-inch by six-inch stabilizer plates with thirteen-sixteenths-inch diameter holes. Bottom chords of joists are left unwelded to the stabilizer plates unless otherwise noted. Erection bolts are mandated for all joists spanning forty feet or greater and for members framing directly into columns.
