About this detail

A thickened concrete slab-on-grade footing supports a stair connection. The assembly features a one-foot-thick thickened concrete footing measuring two feet wide at the base, reinforced with two number five continuous bars and number five bars spaced at twelve inches on center. A felt bond breaker and insulation are placed beneath the concrete slab-on-grade. The stair stringer attachment to the slab is provided by the stair supplier and is detailed to accommodate inelastic seismic story drift as specified in the general structural notes. Stair framing conditions are coordinated per the architectural drawings.
