ASTM A706 Grade 80 reinforcing steel shall not be used for oversized shafts where in-ground plastic hinging is considered as a part of the Earthquake-Resisting System (ERS). ASTM A706 Grade 80 reinforcing steel shall not be used for transverse reinforcement in members resisting torsion. For seismic hooks, f y shall not be taken greater than 75 ksi.

Corrosion performance of conventional (ASTM A615) and Abstract. Conventional reinforcing steel is used in the majority of reinforced concrete structures. In general, steel reinforcement meeting ASTM A615 specifications has been the predominant reinforcement used for these structures. Low-alloy reinforcing steel (ASTM A706) was developed and is being marketed to improve ductility and weldability deficiencies associated with the ASTM A615 reinforcement.
Mar 01, 2005 · The ACT samples with ASTM A615 steel reinforcement had one 12-h potential gradient applied each day for 5 days. Because the ASTM A706 exhibited a lower critical chloride threshold value in the preliminary tests, the ACT samples containing this reinforcement type had a potential gradient applied for 12 h each day for 4 days.

Practice What You Preach:Tips for Welding RebarSep 22, 2017 · This is because the tensile strength of the A615 rebar is 90,000 psi while the A706 rebar is only 80,000 psi. In addition to the preheat and filler requirements listed in AWS D1.4, there is also a section illustrating the allowable types of joint welds.
Oct 31, 2009 · The C.E. of ASTM A615 rebar generally falls between 0.6 and 0.7so preheat is almost always required for welding. ASTM A706 is a rebar intended for applications requiring controlled tensile properties (i.e. seismic applications) and applications requiring enhanced weldability. It is available in only one grade, Grade 60 (Fy = 60 ksi).

STRUCTURE magazine New Trends in Reinforcing Steel (a) ASTM A706, Grade 60 (b) ASTM A615, Grade 40 provided the requirements in (i) and (ii) are satisfied; and ASTM A615, Grade 60 provided the requirements in (i) through (iii) are satisfied. (i) Actual yield strength based on mill tests does not exceed f y by more than 18,000 psi.
Threaded Rebar - Portland BoltA706 Threaded rebar is used as an alternative anchoring method when securing sign structures, wind towers, structural steel, and other foundation applications. These rods are most commonly made from ASTM A615 Grade 75 rebar with a minimum yield strength of 75 ksi.
Oct 28, 2007 · A couple points of interest regarding A706:The carbon equivalent is controlled so as to not exceed 0.55%, so under normal conditions, no preheat is required for commonly used bar sizes (up to #6). Typically, embedded attachments are designed so that they must develop the full tensile capacity of the rebar, so, a minimum weld is required.January 1, 2020 - Cascade SteelA615-18 and ASTM A706-16 Grade 60 or 80 meets the requirements of both specifications as permitted by Section 19.3.3 of A615 and 19.3.3 of A706.
