Technical Note ETN-D-6-20 - 10 pp.; 2020

Grade 60 reinforcing steel, with a yield strength of 60,000 psi, is the most commonly used grade in North America. Recent advances, including substantial new research, have enabled reinforcing steels of higher strengths to be a viable option in a variety of applications in reinforced concrete structures.

The purpose of this Technical Note is to summarize the requirements in ACI 318-19 related to Grade 100 reinforcing bars. Permissible applications of high-strength steel reinforcement (that is, reinforcement with a yield strength of 80,000 or 100,000 psi) were significantly expanded in the 2019 edition of Building Code Requirements for Structural Concrete and Commentary (ACI 2019). Industry professionals should find the information useful when designing, detailing, and specifying Grade 100 reinforcing bars in building projects. Benefits related to the use of Grade 100 reinforcing bars are also included.
