60 ksi. For the Grade 72.5 re- bars, about 50 % of the re-bars did not reach the prescribed minimum yield strength of 72.5 ksi.The experimental curves were then compared with an idealized stress-strain curve developed by using a fractional equation. It is recommended that instead of producing Grade 72.5 ksi reinforcing bars, ...
Characteristic yield strength values of common steel reinforcement specified in the EN 1992 range from 400 MPa to 600 MPa. In the United States, ASTM standardized properties of reinforcing steel are widely used; and the yield strengths of commonly used steel grades (Grade 40, 50, 60, 75...
