Lecture 30 - Page 1 of 9 Lecture 30 – Development of Reinforcement, Splices, Hooks Reinforcing bars must be embedded a minimum distance into the concrete in order to achieve the full tensile capacity, T of the bar. This length is referred to as “Development Length”, Ld. The development length is based upon the BONDbetween the rebar and the concrete. Factors affecting this bond include the following: •Type of ribbing on the bar •Presence of epoxy (or other ) coating •Concrete quality •Distance between bar and edge of concrete •Type of end anchorage into the concrete Concrete LdRebar T = Asfy
