A structural steel floor beam receives a hanger member connecting to the stair midlanding and floor beam, provided by the stair supplier. The connection occurs at the centerline of the beam, with web stiffeners added per general structural notes. A broken-back hollow structural section or channel stair stringer frames into an HSS or channel landing beam. Stair deck is omitted for clarity.
