DEVELOPMENT OF STANDARD SPECIFICATIONS FOR BENDING/STRAIGHTENING CONCRETE REINFORCING STEEL. FINAL REPORT

This report describes the results of laboratory experiments in which concrete reinforcing steel of various sizes was "cold" and "hot" bent under different conditions and was subsquently straightened. The bent/straightened steel was inspected for cracking and tested in tension for strength and ductility. The laboratory data were analyzed to determine the conditions that may cause reinforcing bars to crack during bending/straightening operations, or that may render the engineering properties of bars unsuitable for reinforcing the concrete. The results of those analyses were used to propose standard specifications for bending/straightening reinforcing bars, for WSDOT's considerations.
