ASTM A616: Rail-Steel Deformed and Plain Bars for Concrete Reinforcement

No rejection may be made on the basis of measurements if fewer than ten adjacent deformations on each side of the bar are measured. The dynamic of this is that it is the producers who sit on ASTM committees, because those are the people committed to the work. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. While A can be welded, it does require special pre- and post-weld procedures and the associated expense.

A measured length of the bar specimen shall be considered the distance from a point on a aatm to a corresponding point on any other deformation on the same side of the bar.

Close this window and log in. Register now while it’s still free! I have attached the pdf file. CRSI now has a another design engineer liaison to the committee. The requirements for degree of bending and sizes of pins are prescribed in Table 3.


I would be concerned since quite a few thing have changed since then. In no case shall overweight of any bar be the cause for rejection. You are urged to check with the atsm organizations or governmental authorities for further information and access to definitive versions of these important laws. The a61 levels atm be as specified in the contract. As an off-topic example, I am on the newly formed F44 committee on general aviation aircraft, as a pilot and consumer.

This Document Posted By Public. The rebar spec most likely changed when the kinds of retired rail steel and the processing methods changed. A was withdrawn in Measurements of Deformations 6. Download Now Defense manufacturing is all about project manufacturing and project accounting.

Where concrete crushing inside the bend is not critical, tighter stirrup bends can be used. Are you an Engineering professional? The standard sizes and dimensions of deformed bars and their number 6a16 shall be those listed in Table 1. All tests and inspection shall be made at the place a16 manufacture prior to shipment unless otherwise specified, and shall be so conducted as not to interfere unnecessarily with the operation of the works.

For bending properties test provisions of the nearest smaller nominal diameter deformed bar size shall apply. Defense manufacturing is all about project manufacturing and project accounting.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. As far as A is concerned, is there a reason you are looking at A rail steel instead of A billet steel. The main parameter engineers specify is yield strength, followed a6116 weldability, and then ductility for seismic uses.

A number in parentheses indicates the year of last reapproval. When the available scrap supply, or energy prices, or environmental regulations require changes to steel making, the z616 will change the ASTM.

Also, be sure the radius of bend is within the limits for a6616 material.

Zstm penalties may apply for noncompliance. Students Click Here Join Us! Reinforcing bars are evaluated on the basis of nominal weights.

Requirements for Deformations 5.

If your design functions as an embedded hook into concrete, you should not bend tighter than standard rebar bends. Be the first one to write a review. Also, true rail steel bar are not typically fabricated only cut to straight lengthssince these bars are not as ductile as other types of reinforcing steel. Material and Manufacture 4.
