1、Designation: A1035/A1035M 11A1035/A1035M 13Standard Specification forDeformed and Plain, Low-carbon, Chromium, Steel Bars forConcrete Reinforcement1This standard is issued under the fixed designation A1035/A1035M; the number immediately following the designation indicates theyear of original adoptio
2、n or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers low-carbon, chromium, steel bars, deformed and p
3、lain for concrete reinforcement in cut lengthsand coils. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. The text of thisspecification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those
4、intables and figures) shall not be considered as requirements of the specification.21.2 Bars are of two minimum yield strength levels as defined in 9.2: namely, 100 000 psi 690 MPa, and 120 000 830 MPadesignated as Grade 100 690 and Grade 120 830, respectively.NOTE 1Caution: Designers need to be awa
5、re that typical design standards limit the design strength to 80 000 psi 550 MPa, except for prestressingsteel and for spiral transverse reinforcement. Members reinforced with bars with yield strengths that are considerably above 80 000 psi 550 MPa mayexhibit behavior that differs from that expected
6、 of conventional reinforced concrete members or may require special detailing to ensure adequateperformance at service and factored loads.1.3 Deformed bars shall have a minimum yield strength and other tensile properties in accordance with Table 2. Hot-rolled plainrounds in sizes up to and including
7、 2.25 in. 57.2 mm in diameter in coils or cut lengths when specified for dowels, spirals,structural ties or bar supports shall be furnished under this specification and shall also meet the tensile properties requirements ofTable 2. Ductility properties for plain rounds shall be those of the nearest
8、smaller nominal diameter deformed bar size in Table2. Requirements covering deformation dimensions and marking are not applicable to plain rounds.NOTE 2Welding of the material in this specification should be approached with caution since no specific provisions have been included to enhanceits weldab
9、ility. When this steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used.1.4 Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specifiedby the purchaser (see 4.1.10).1.5 Thi
10、s specification is applicable for orders in either inch-pound units (as Specification A1035) or in SI units (as SpecificationA1035M).1.6 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shownin brackets. The values stated in e
11、ach system are not exact equivalents; therefore, each system must be used independently of theother. Combining values from the two systems may result in nonconformance with the specification.2.

38、. The deformations on opposite sides of thebar shall be similar in size, shape, and pattern.7.2 The deformations shall be placed with respect to the axis of the bar so that the included angle is not less than 45. Wherethe line of deformations forms an included angle with the axis of the bar from 45

41、the nominal perimeter of the bar.Where the ends terminate in a longitudinalrib, the width of the longitudinal rib shall be considered the gap. Where more than two longitudinal ribs are involved, the totalwidth of all longitudinal ribs shall not exceed 25 % of the nominal perimeter of the bar; furthe

Measurements of Deformation8.
43、1 The average spacing of deformations shall be determined by measuring the length of a minimum of 10 spaces and dividingthat length by the number of spaces included in the measurement. The measurement shall begin from a point on a deformation atthe beginning of the first space to a corresponding poi
44、nt on a deformation after the last included space. Spacing measurements shallnot be made over a bar area containing bar marking symbols involving letters or numbers.8.2 The average height of deformations shall be determined from measurements made on not less than two typical deformations.Determinati
45、ons shall be based on three measurements per deformation, one at the center of the overall length and the other twoat the quarter points of the overall length.8.3 Insufficient height, insufficient circumferential coverage, or excessive spacing of deformations shall not constitute cause forrejection
46、unless it has been clearly established by determinations on each lot tested that typical deformation height, gap, or spacingdo not conform to the minimum requirements prescribed in Section 7. No rejection shall be made on the basis of measurementsif fewer than ten adjacent deformations on each side
47、of the bar are measured.9. Tensile Requirements9.1 The material, as represented by the test specimens, shall conform to the requirements for tensile properties prescribed inTable 2.9.2 The yield strength shall be determined by the offset method (0.2 % offset), described in Test Methods and Definitio
