Are ASTM F1554 Grade 55 anchor rods > 2” in diameter a ‘ductile steel element’ per ACI 318-05 Appendix D.1?
According to ACI 318-05 Appendix D.1, a “Ductile Steel Element” is an element with a tensile test elongation of at least 14 percent and reduction in area of at least 30 percent. The minimum elongation percentage for any diameter of F1554 Grade 55 anchor rod is 21% and the minimum reduction of area percentage is 30%. Therefore, any diameter of Grade 55 anchor rod would meet or exceed the ACI requirement for a “Ductile Steel Element”. We can Refer to our ASTM F1554 Summary Page for complete mechanical requirements for the F1554 specification.
