Static and dynamic properties were gathered for bars satisfying ASTM A615,A15,A432,A431,and A706,with yield stresses ranging from 42 ksi (290 MPa) to 103 ksi (710 MPa).Strength enhancement with strain rate was expressed in the form of a dynamic increase factor (DIF) defined as the ratio of the dynamic to static yield (or ultimate) stress.New Trends in Reinforcing Steel High-Strength Reinforcing Apr 14,2019 ASTM A432#0183;The following is a brief history of the appearance and adoption of the various grades of reinforcing bars in ASTM specifications and ACI 318 Grades 33,40,and 50 were in common use from the early 1900s through the early 1960s.Grades 60 and 75 reinforcing bars appeared in 1959 with the publication of ASTM A432 and ASTM A431,respectively.

Historical Reinforcement Bar sizes and strength

Jul 24,2002 ASTM A432#0183;ACI 318-56 was the last to use ASTM A305(Grade 40) bars; ACI 318-1963 brought ASTM A432 and A61 (Grade 60) bars in to replace them.By 1967,most projects used Grade 60 bars.JAE is on target with the designation.An S before the bar often indicates a slab use.High-Strength Reinforcing Bars Technical NoteASTM A432 (ASTM 1959a) and ASTM A431 (ASTM 1959b),respectively. The 1963 edition of ACI 318 allowed the use of reinforcing bars with a yield strength of 60,000 psi. In 1968,ASTM A615 first appeared,which included Grades 40,60,and 75 deformed reinforcing bars. Grade 75 bars appeared inHigh Strength astm a615 deformed in coil - Low Carbon Standard Specification for Deformed and Plain astm (A) The nominal dimensions of a deformed bar are equivalent to those of a plain round bar having the same weight [mass] per foot [metre] as the deformed bar.1.2 Grade Bars are of two minimum yield strength levelsnamely,60 000 psi [420 MPa] and 80 000 psi [550 MPa],designated as Grade 60 [420] and Grade 80 [550],respectively.
