RE: ASTM Standard

[Subject Prev][Subject Next][Thread Prev][Thread Next]
To connect all of the pieces of this puzzle, get a copy of CRSI Engineering Data Report Number 48 "Evaluation of Reinforcing Bars in Old Reinforced Concrete Structures". Ths ASTM A 305 specified the deformations of the reinforcing steel and existed from 1947 to 1968 when it was replaced by ASTM A 615 which included deformation specifications AND material specifications. The A 305 bar was generally linked to A15 for material properties that would designate reinforcing steel as: structural Fy=33 ksi, intermediate Fy=40 ksi, or hard Fy=50 ksi.

I have a copy of the A 305-50T that was included in my CRSI Design Handbook 1952.

 I am looking for an yield strength of steel based on
ASTM A305-56T.

I have both 1996 and 2004 editions but it does not cite A305

I have looked at old books. They do refer to ASTM A305 with fs = 30,000

I am interested in fy value.

Please let know, if list server(s) hasthe fy value.
