About this detail

Reinforced concrete tilt-up wall panel openings require specific rebar placement around all perimeter edges and corners to control stress concentrations. Two number five bars run horizontally above and below the opening, extending forty bar diameters beyond the edge of the opening. Two number five bars run vertically on each side of the opening, also extending forty bar diameters beyond the edge. One number five by four-foot diagonal bar is centered at each corner of all typical openings. A minimum one-foot-six-inch edge distance must be maintained from the opening to the nearest panel edge. If the reinforcing bar cannot be extended forty bar diameters beyond the opening, the bar extends the maximum available distance and terminates with a standard hook.
