A concrete tie beam is positioned beneath a slab on grade, featuring two number five top and bottom longitudinal reinforcing bars. The eighteens-inch square profile incorporates number four closed ties spaced per the elevation, with three inches of typical concrete clearance maintained around the perimeter. End conditions require reinforcing bars to extend to the opposite end with ninety-degree standard hooks or lap splice dowels through the footing at intermediate conditions. The adjoining slab on grade transitions symmetrically from the center line of the tie beam with varying depths specified per plan.
