Abstract
Current structural design codes in the United States treat the development of straight bars/lap splices, standard hooks, and deformed headed bars with separate equations. The fib Model Code 2010, on the other hand, uses a more unified approach. Recent changes to the standard hook and headed bar equations in the ACI 318–19 Building Code Requirements for Structural Concrete have sparked conversation about the discrepancies between ACI 318–19 and the AASHTO LRFD Bridge Design Specifications within the bridge design community. The objective of this research was to develop and validate a unified approach for the design/evaluation of reinforcement anchorage. A procedure based on the partly cracked elastic stage of bond was proposed. The proposed procedure was validated with 1006 tests from the literature.
