About this detail

Beam bracing at an eccentric stair hanger condition transfers a maximum factored applied moment of seventy kip-inches. A structural steel angle spanning three steel deck flutes minimum is anchored with one half-inch diameter cast-in-place anchor in each flute with a three-and-a-quarter-inch minimum embedment. An angle member connects back to the supporting beam flange with a one-quarter-inch plate at each end and one seven-eighth-inch diameter A325 bolt at each end. Concrete on metal deck with welded wire reinforcement of size six by six and W2.9 by W2.9 sits perpendicular to the beam. A stiffener plate and stair hanger are provided per the stair supplier, with the contractor responsible for coordinating locations.
