About this detail

Standard hook configurations for concrete reinforcing bars specify finished inside bend diameters based on bar sizes, requiring six times the bar diameter for numbers three through eight, eight times for numbers nine through eleven, and ten times for numbers fourteen and eighteen. Extension lengths vary with twelve times the bar diameter for certain hooks and four times the bar diameter with a minimum of two and one-half inches for others. Supplementary ties, spandrel ties, and stirrups include cross-tie arrangements with alternating end orientations and specific dimensional clearances.
