A stair stringer bears onto a thick Teflon bearing pad resting on an embed plate with HSA anchors cast into a concrete over metal floor deck assembly. The support framing utilizes web stiffeners on each side at the stair attachment to transfer loads to the underlying structural steel beam. A stair restraint by the supplier is detailed to accommodate seismic drift per general structural notes. The stair designer must notify the engineer of record of any applied moment.
