All Thread A615 Rebars in Lieu of F1554 Anchor Rods?
I was asked to review calculations and drawings for the foundation design for an out-of-state supplier of wind turbines. I noticed on the drawings that they called for #7 A615 Grade 75 "Anchor Bolts" and immediately marked the drawings and calcs that A615 Grade 75 is a rebar designation, and that F1554 (Gr 36, 55, or 105) was the proper spec for "Anchor Rods." After an internet search, I have now seen that there are in fact A615 Gr 75 all-thread rebars, though it appears they are mostly used in soil nail and ground tie-back applications.
Is this a common anchor rod spec the wind turbine industry? Is there any reason that I should reject the calcs and ask that they be based on F1554? Is there any ACI or other code provisions that address this? If it is code-compliant and OK to use A615 all-thread rebar for anchor rods, are there any other negative things I should be aware of?
Thanks in advance.
