1、Designation: A615/A615M 181American Association State Highway andTransportation Officials StandardAASHTO No.: M 31Standard Specification forDeformed and Plain Carbon-Steel Bars for ConcreteReinforcement1This standard is issued under the fixed designation A615/A615M; the number immediately following
2、the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved fo
3、r use by agencies of the U.S. Department of Defense.1NOTEEditorial corrections were made throughout in July 2018.1. Scope*1.1 This specification covers deformed and plain carbon-steel bars in cut lengths and coils for concrete reinforcement.AnnexA2 of this specification covers deformed bars for use
4、forother applications. Steel bars containing alloy additions, suchas with the Association for Iron and Steel Technology and theSociety of Automotive Engineers series of alloy steels, arepermitted if the resulting product meets all the other require-ments of this specification. The standard sizes and
5、 dimensionsof deformed bars and their number designations are given inTable 1.1.2 Unless specified for use for other applications in AnnexA2, bars are of four minimum yield strength levels: namely,40 000 psi 280 MPa, 60 000 psi 420 MPa, 80 000 psi 550MPa, and 100 000 psi 690 MPa, designated as Grade
6、 40280, Grade 60 420, Grade 80 550, and Grade 100 690,respectively.NOTE 1Grade 100 690 reinforcing bars were introduced in thisspecification in 2015. In contrast to the lower grades, which have ratios ofspecified tensile strength to specified yield strength that range from 1.31to 1.5, Grade 100 690
7、reinforcing bars have a ratio of specified tensilestrength to specified yield strength of 1.15. Designers should be aware thatthere will, therefore, be a lower margin of safety and reduced warning offailure following yielding when Grade 100 690 bars are used instructural members where strength is go
8、verned by the tensile strength ofthe reinforcement, primarily in beams and slabs. If this is of concern, thepurchaser has the option of specifying a minimum ratio of tensile strengthto actual yield strength. Consensus design codes and specifications such as“Building Code Requirements for Structural
9、Concrete (ACI 318)” may notrecognize Grade 100 690 reinforcing bars: therefore the 125 % ofspecified yield strength requirements in tension and compression are notapplicable. Mechanical and welded splices should meet a minimumspecified tensile strength of 115 000 psi 790 MPa.NOTE 2Designers need to
10、be aware that design standards do notrecognize the use of the No. 20 64 bar, the largest bar included in thisspecification. Structural members reinforced with No. 20 64 bars mayrequire approval of the building official or other appropriate authority andrequire special detailing to ensure adequate pe
11、rformance at service andfactored loads.1.3 Plain bars, in sizes up to and including 212 in. 63.5 mmin diameter in coils or cut lengths, when ordered shall befurnished under this specification in Grade 40 280, Grade 60420, Grade 80 550, and Grade 100 690. For ductilityproperties (elongation and bendi
12、ng), test provisions of thenearest smaller nominal diameter deformed bar size shallapply. Requirements providing for deformations and markingshall not be applicable.NOTE 3Welding of the material in this specification should beapproached with caution since no specific provisions have been includedto
13、enhance its weldability. When this steel is to be welded, a weldingprocedure suitable for the chemical composition and intended use orservice should be used. The use of the latest edition of AWS D1.4 D1.4Mis recommended. The AWS D1.4 D1.4M Welding Code describes theproper selection of the filler met
14、als and preheat/interpass temperatures, aswell as performance and procedure qualification requirements.1.4 Requirements for alternate bar sizes are presented inAnnex A1. The requirements in Annex A1 only apply whenspecified by the purchaser (see 4.2.5).1.5 The text of this specification references n
15、otes andfootnotes which provide explanatory material. These notes andfootnotes (excluding those in tables) shall not be considered asrequirements of the specification.1.6 This specification is applicable for orders in eitherinch-pound units (as Specification A615) or in SI units (asSpecification A61
16、5M).1.7 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard. Within the text, theSI units are shown in brackets. The values stated in eachsystem may not be exact equivalents; therefore, each systemshall be used independently of the other. Combining value
17、sfrom the two systems may result in non-conformance with thespecification.1This specification is under the jurisdiction of ASTM Committee A01 on Steel,Stainless Steel and Related Alloys and is the direct responsibility of SubcommitteeA01.05 on Steel Reinforcement.Current edition approved July 1, 201
