About this detail

Standard reinforcing bar hook and bend configurations detail standard dimensions and bend diameters for various bar sizes. For all reinforcing except column ties and beam stirrups, bend diameters D equal six times the bar diameter for number three through number eight bars, eight times the bar diameter for number nine, number ten, and number eleven bars, and ten times the bar diameter for number fourteen and number eighteen bars. Beam stirrups and column ties specify bend diameters D equal to four times the bar diameter for number three, number four, and number five bars, and six times the bar diameter for number six, number seven, and number eight bars. Specific hook angles including ninety degrees, one hundred eighty degrees, and one hundred thirty-five degrees are detailed with corresponding extension lengths and minimum requirements.
