The scope of this article is to provide preferred detailing practices for inhouse structural drawings for the purpose of decreasing detailing hours by reducing. It is informational only and not an official part of the standard the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Scope. 1. 1 This specification covers deformed and plain carbon steel bars in cut lengths and coils for concrete reinforcement. Concrete Reinforcement Detailing Pdf' title='Concrete Reinforcement Detailing Pdf' />Steel bars containing alloy additions, such as with the Association for Iron and Steel Technology and the Society 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. Bars are of five minimum yield strength levels namely, 4. MPa, 6. 0 0. 00 psi 4. MPa, 7. 5 0. 00 psi 5. MPa, 8. 0 0. 00 psi 5. MPa, and 1. 00 0.

In contrast to the lower grades, which have ratios of specified tensile strength to specified yield strength that range from 1. Grade 1. 00 6. 90 reinforcing bars have a ratio of specified tensile strength to specified yield strength of 1. Designers should be aware that there will, therefore, be a lower margin of safety and reduced warning of failure following yielding when Grade 1. 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 3. Grade 1. 00 6. 90 reinforcing bars therefore the 1. Mechanical and welded splices should meet a minimum specified tensile strength of 1. MPa. Note 2 Designers need to be aware that design standards do not recognize the use of the No. Structural members reinforced with No. Plain bars, in sizes up to and including 2. Grade 4. 0 2. 80, Grade 6. Grade 7. 5 5. 20, Grade 8. Grade 1. 00 6. 90. For ductility properties elongation and bending, test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Requirements providing for deformations and marking shall not be applicable. Note 3 Welding of the material in this specification should be approached with caution since no specific provisions have been included to enhance its weldability. When this steel is to be welded, a welding procedure suitable for the chemical composition and intended use or service should be used. The use of the latest edition of AWS D1. D1. 4. M is recommended. The AWS D1. 4D1. M Welding Code describes the proper selection of the filler metals and preheatinterpass temperatures, as well as performance and procedure qualification requirements. Requirements for alternate bar sizes are presented in Annex A1. The requirements in Annex A1 only apply when specified by the purchaser see 4. The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes excluding those in tables shall not be considered as requirements of the specification. This specification is applicable for orders in either inch pound units as Specification A6. SI units as Specification A6. M. 1. 7 The values stated in either inch pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents therefore, each system shall be used independently of the other. Combining values from the two systems may result in non conformance with the specification. This specification does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this specification to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
