About this detail

Standard reinforcement end hooks and bend geometries provide development lengths for deformed bars, ties, and stirrups. The diagrams illustrate 90-degree, 45-degree, 135-degree, and 180-degree bends with corresponding extensions such as 12d and 4d plus minimum dimensions like two and a half inches or three inches. Minimum inside bend diameters for deformed bars are specified as six times bar diameter for number three through number eight, eight times for number nine through number eleven, and ten times for number fourteen through number eighteen. Minimum inside bend diameters for ties and stirrups are four times bar diameter for number three through number five, and six times for number six through number eight. All hooks shall be 90-degree or 180-degree standard hooks unless otherwise shown or noted.
