About this detail

Structural steel framing and truss bracing conditions occur at a roof step transition. The steel column supports a joist girder seat connected via a bearing plate with two three-quarter-inch diameter A325N bolts through three-inch long slotted holes, leaving the joist girder seat left unwelded to the bearing plate. Additional members include a half-inch by five-inch by one-foot stiffener plate welded with five-sixteenth-inch fillet welds on all sides, three-quarter-inch thick web plates on each side, and a half-inch by six-inch by six-inch stabilizer plate. Metal roof decks bear on steel joists and steel beams equipped with web stiffeners on each side. Angle kickers and metal stud walls are tied back to the structure with provisions for vertical deflections.
