Standard Specification for Billet-Steel Bars for Concrete Reinforcement (a) These specifications cover two classes of billet-steel concrete reinforcement bars: namely, plain and deformed. A deformed bar is defined as a bar which conforms to the latest issue of the...
History of Reinforcing Steel
ASTM A15 revised by adding grade 40. The American Association of State Highway Officials (AASHO) issued its first standard for concrete reinforcement, AASHO M 31. First hot-dip galvanized reinforcing bar specifications published, ASTM A123. ASTM A305 published; it included rebar deformation patterns.

Yield Stress for Old Reinforcing Bars 2 - Eng-Tips
2006年4月6日 · "Normal reinforcing steel ultimate strength of between 50,000 - 70,000 lbs per sq in with elastic limit (yield) at 25,000 - 35,000 lbs per sq in. Cold working the bars will raise the elastic limit to 40,000 - 50,000 lbs per sq in. Deformed bars have a higher elastic limit claimed at 50,000 - 65,000 lbs per sq in."
Steel Reinforcing Bar Specifications in Old Structures
1999年4月1日 · In 1950, A 15 specified all reinforcing bars as round (#3 through #11) with A 305 deformation patterns. In 1964, A 408 added sizes #14S and #18S, and two strength levels: A 432 (Grade 60 - 414 MPa) and A 431 (Grade 75 - 517 MPa). Finally, during 1968, ASTM combined all previous reinforcing bar specifications into A 615.
