A stair hanger and three-eighths-inch stiffener plate connect to a steel beam per plan, supporting a concrete slab on metal deck with welded wire reinforcement. Shear studs are spaced at a maximum of twelve inches on center along the beam centerline. The contractor must coordinate the exact location of the stiffener plate with the stair supplier. The maximum factored applied moment is twenty kip-inches.
