About this detail

Standard reinforcement details define standard hook dimensions, bend diameters, stirrup configurations, and lap splice lengths for various rebar sizes. A standard hook features a bend diameter of six bar diameters for number three through number eight bars, eight bar diameters for number nine through number eleven bars, and ten bar diameters for number fourteen through number eighteen bars. A typical lap splice requires sixty-four bar diameters for number three through number six bars, and eighty bar diameters for number seven through number eleven bars, wired together. Stirrup and tie hooks specify bend diameters greater than four bar diameters for number three through number five bars with ninety-degree and one-hundred-thirty-five-degree bends. A typical closed tie shows standard corner bends and extension lengths. Notes specify that "d" is the nominal diameter of the bar in inches, and all splices unless noted otherwise on drawings shall be staggered twenty-four inches.
