About this detail

An eccentric stair hanger connects to a wide flange beam adjacent to a stairwell using two seven-eighths inch diameter ASTM A325 slip-critical bolts and plates whose thickness and width match the beam flange. A three-eighths inch fitted stiffener is provided where indicated as TCS, with a matching far side stiffener where a vertical stiffener occurs. The eccentric stair hanger is supplied by the stair contractor, who must submit shop drawings showing all load magnitudes, directions, locations, and connection conditions.
