1. Sco Scope* pe* 1.1 This specification specification covers deformed and plain carbonsteel bars in cut lengths and coils for concrete reinforcement. Steel bars containing alloy additions, such as with the Associatio cia tion n fo forr Ir Iron on an and d St Stee eell Tech echno nolo logy gy an and d th thee So Socie ciety ty of Automotive Engineers series of alloy steels, are permitted if the resulting product meets all the other requirements of this specification. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. 1. 1.2 Bars are of five minimu minimum m yield strength levels: namely, namely, 40 000 psi [280 MPa], 60 000 psi [420 MPa], 75 000 psi [520 MPa], 80 000 psi [550 MPa], and 100 000 psi [690 MPa], designated as Grade 40 [280], Grade 60 [420], Grade 75 [520], Grade 80 [550], and Grade 100 [690], respectively. NOTE 1—Grade 1—Grade 100 [690] reinforcing reinforcing bars were introd introduced uced in this specification in 2015. In contrast to the lower grades, which have ratios of specified tensile strength to specified yield strength that range from 1.31 to 1.5, Grade 100 [690] reinforcing bars have a ratio of specified tensile strength to specified yield strength of 1.15. Designers should be aware that there will, therefore, be a lower margin of safety and reduced warning of failu fa ilure re fo foll llow owin ing g yi yield eldin ing g wh when en Gr Grad adee 10 100 0 [6 [690 90]] ba bars rs ar aree us used ed in structural members where strength is governed by the tensile strength of the reinforcement, primarily in beams and slabs. If this is of concern, the purchaser has the option of specifying a minimum ratio of tensile strength to actual yield strength. Consensus design codes and specifications such as “Building Code Requirements for Structural Concrete (ACI 318)” may not recogn rec ognize ize Gra Grade de 100 [690] rei reinfo nforci rcing ng bar bars: s: the theref refore ore the 125 % of specified yield strength requirements in tension and compression are not applica app licable ble..
