When it was withdrawn, there were astk grades, namely 50 ksi and 60 ksi, so you may be looking at a much older version. A was withdrawn in This specification has been approved,for use by agencies of the Department of Defense and for listing in the DoD Index of Specifications and Standards. Producers try to respond to market pressure higher strength, for examplebut there are complications, like ACIwhich limits the use of high strength bars for functional and safety reasons.
Reinforcing bars are evaluated on the basis of nominal weights. In addition, standards bodies will frequently issue errata or reissue standards over time and governmental bodies may change which aatm they incorporate to law. The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
If your design functions as an embedded hook into concrete, you should not bend tighter than standard rebar bends. A661 dynamic of this is that it is the producers who sit on ASTM committees, because those are the sstm committed to the work.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
I have attached the pdf file. Tighter bends may damage the bar and could present a hazard to the persons doing the bending. This Document Posted By Public. The main parameter engineers specify is yield strength, followed by weldability, and then ductility for seismic uses.
When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the producers will change the ASTM. The nominal perimeter of the bar shall be 3. Note 1—The values stated in inch-pound units are to be regarded as the standard. The standard sizes and dimensions of deformed x616 and their number designations shall be those listed in Table 1.
ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement
Awtm tests and inspection shall be made at the place of manufacture prior to shipment unless otherwise specified, and shall be so conducted as not to interfere unnecessarily with the operation of the works. The lesson I am learning is that the replacement standard is not a direct substitute for the old standard.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

If structural engineers were more involved in the A Are you an Engineering professional? Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Where concrete crushing inside the bend is not critical, astmm stirrup bends can be used. As far as A is a166, is there a reason you are looking at A rail steel instead of A billet steel.
The yield load- shall be recorded when the total gage length under load becomes 1 8. It’s easy to join and it’s free.
