To support the adoption of high-strength reinforcement (fy > 60 ksi) into widespread use, it is fundamental that appropriate development and splice lengths be calculated. The objective of this research is to evaluate the development of high-strength reinforcing steel and establish a design expression for the development and splicing of this steel. Two phases of experimental tests were conducted along with analytical evaluation. Based on the research, a design expression was developed that will enable appropriate design and detailing of concrete structures containing high-strength reinforcement.
