Influence of Casting Position and Shear on Development and Splice Length-- Design Recommendations

J. O. Jirsa and J. E. Breen


In Report 242-1, "The Influence of Casting Position on Development and Splice Length of Reinforcing Bars," and Report 242-2, "The Influence of Shear on Lapped Splices in Reinforced Concrete," the details and results of the experimental investigatoin on the influence of casting position and shear on splice and development length were presented.

Based on the test results, suggestions are made for revising specifications for "top reinforcement" development and splice length as a function of casting position and concrete slump characteristics. The influence of shear and transverse reinforcement geometry is discussed and suggestions made for design applications.
