Abstract:
A straightforward, orderly procedure for calculating total embedment distance from critical section to tip of the end hook is presented. This procedure carefully seperates code factors applicable to (a) the hook proper, (b) the straigt "lead-in" length, and (c) the equvilant straight embedment replaced by the hook plus lead-in. The interpretation of "Buiulding Code Requirements for Reinforced Concrete (ACI 318-77)" yields results compatible with research developed since 1975 but not yet incorporated into the code. The design procedure also suggests a pattern for future code revisions to reflect recent research without ambiguity.
