About this detail

Reinforcing bar development lengths, Type B lap splice lengths, and hook development lengths for concrete construction are detailed. Design criteria for Grade 60 reinforcing bars are provided, specifying multiplier adjustments for higher steel grades up to Grade 80, epoxy-coated reinforcement, and lightweight aggregate concrete. Additional notes dictate requirements for splicing bars of different sizes, staggering splices, coupler or welded splice options, and spacing clearances. Tension lap splices are prohibited for number 14 and number 18 bars.
