Reinforcing Bar Laps and Standard Hooks

About this detail

This drawing outlines standard detailing requirements for reinforcing steel including lap splices, standard hooks, and bend diameters. Tabulated lap splice lengths apply to normal weight concrete and uncoated reinforcing steel, with specific adjustments for light weight concrete, epoxy-coated bars, bundle bars, top bars, and compression splices. Standard hooks are detailed for 90-degree, 180-degree, and 135-degree configurations showing critical concrete planes, development lengths, and bend diameters indexed by bar size. General notes define parameters for Case 1 and Case 2 splice conditions based on concrete cover and bar spacing.
