A structural steel floor beam receives a hanger member at its centerline, which connects top and bottom to a stair midlanding beam. The floor beam features a web stiffener per general structural notes. The stair midlanding uses an HSS or channel landing beam framing into a broken-back HSS or channel stair stringer, with all hanger and landing connections provided by the stair supplier. When the stair landing beam is eccentric from the floor beam above, a separate offset detail governs.
