ASTM A706 rebar is a specification given to low-alloy reinforcing bars in either standard lengths or coiled configurations. This rebar grade is processed in open hearths, electric furnaces, or basic oxygen furnaces and is available in numerous grades, including grade 60 and grade 80. A706 rebar is a weldable rebar and especially recommended for Advancing the Seismic Implementation of High Strength Oct 17, 2019 · Grade 80 reinforcement is already included in ASTM A706, which is the specification for reinforcing bars in earthquake-resistant structures. Based on current research, and because a Grade 80 ASTM A706 specification already exists, the adoption of Grade 80
In 2012, two local agency projects in Oregon used ASTM A706, Grade 80 steel reinforcement in large diameter drilled shafts for crossings of the Willamette River in Portland. One is the Tilikum Crossing, a cable-stayed bridge carrying a transit line and pedestrians, which is owned by the city of Portland. The other is the Sellwood Bridge, a CRSI:History of Reinforcing SteelSTM A615/A615M revised, adding grade 80. ASTM A706/A706M revised, adding grade 80.

Our reinforcing steel conforms to ASTM A615-18, Grade 40, 60, 75, 80 or 100 or ASTM A706- 16 Grade 60 or 80 as indicated on test reports. The steel shipped is in fact composed of the heats indicated on the Mill Test Report and is represented by results obtained on heat samples tested in accordance with ASTM A615-18 or ASTM A706-16 specifications for sampling, chemical analysis, physical testing and Mixing A706 and A615 Rebar - Structural engineering Dec 23, 2013 · RE:Mixing A706 and A615 Rebar. TXStructural (Structural) 23 Dec 13 14:25. There is no need to mix. The price difference, if you can actually get A615, is inconsequential. Much of the bar in the western states is dual-spec (A615/A706), so you will likely get higher ductility without specifying it. We do not encourage use of A706 elsewhere
Sep 22, 2017 · For example, if an A706 grade 60 bar is welded to a A615 grade 60 bar, the electrodes required for the A615 grade 60 are used. This is because the tensile strength of the A615 rebar is 90,000 psi while the A706 rebar is only 80,000 psi.

Restrictions on the strength of reinforcement in ACI 318 Deformed reinforcement resisting earthquake-induced flexure, axial force, or both, shall comply with ASTM A706, Grade 60. ASTM A615 Grades 40 and 60 reinforcement shall be permitted if:(a) The actual yield strength based on mill tests does not exceed f y by more than 18,000 psi; and (b) The ratio of the actual tensile strength to the actual
- Material PropertiesLimitations and RequirementsBenefits and LimitationsThe Future of HSRBReferencesThe design of any reinforced concrete member must satisfy the fundamental requirements for strength and serviceability as prescribed in ACI 318. With respect to reinforcing bars, the basic mechanical properties that are important in achieving safe and serviceable designs are:1. Yield strength, fy 2. Tensile-to-yield strength ratio, fu/fy 3. Strain (elongation) at tensile strength 4. Length of yield plateau Depicted in Figure 1are typical tensile stress-strain curves for ASTM A615 reinforcing bars of GradeASTM-A706 Standard Specification for Deformed and Plain 1.2 Grade Bars are of two minimum yield strength levels:namely, 60 000 psi [420 MPa] and 80 000 psi [550 MPa], designated as Grade 60  and Grade 80 , respectively. 1.3 Plain bars, in sizes up to and including 2 1 / 2 in.

STRUCTURE magazine Welding Reinforcing Steel:AWS D1.4 Standard specifications for low-alloy steel ASTM A706 limit chemical composition and CE to enhance weldability. However, it is permissible to weld other base metals, such as ASTM A615, which is commonly used in reinforced concrete, as long as the appropriate weld procedure specification (WPS) is followed and correct filler weld metal is used.
Gerdau rebar is produced across our network of North American mills, allowing for fast and efficient service. Selling Formats Typical lengths are 20, 30, 40 and 60 foot, but custom lengths are available. ASTM A615 is produced in grades 40, 60, 75, 80, 100. ASTM A706 is produced in grades 60, 80. CSA 30.18-09 is produced in grades 400R, 400W Welding A706 Rebar - Structural engineering general Jan 06, 2015 · Looking at AWS D1.4 Section 5.1.2 - the filler metal should be selected based on the lower tensile strength base metal. A706 grade 60 reinforcing steel has a tensile strength of 80 ksi. A36 plate has a tensile strength of 58-80 ksi. To me, this means that they have the same tensile strength (using the upper end of the range for the plate).

A wide variety of deformed rebar astm a706 gr60 options are available to you, such as standard, processing service, and grade. how to weld reinforcement bar steel or rebar welding For example, if an A706 grade 60 bar is welded to a A615 grade 60 bar, the electrodes required for the A615 grade 60 are used. This is because the tensile strength of the A615 rebar is 90,000 psi while the A706 rebar is only 80,000 psi.
