About this detail

Concrete wall panels require additional reinforcing steel around openings to control cracking and transfer stresses. One five-foot-four-inch diagonal bar is placed and centered at each corner of all openings as a typical condition. Two number five bars run horizontally above and below the opening, extending forty bar diameters beyond each edge. Two number five bars run vertically on each side of the opening, also extending forty bar diameters beyond the edge. A minimum edge distance of one foot six inches must be maintained from any opening to the nearest panel edge. Unspecified openings exceeding the maximum three-foot height require engineer of record notification. When rebar cannot extend the full forty bar diameters past the opening, bars extend the maximum available distance and terminate with a standard hook.
