Anchoring Components and Structural Supports in Concrete

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-1284, "Anchoring Components and Structural Supports in Concrete." This proposed guide, Revision 1 of Regulatory Guide (RG) 1.199 of the same name, endorses Appendix D, "Anchoring to Concrete," of an updated version of American Concrete Institute code ACI 349, "Code Requirements for Nuclear Safety-Related Concrete Structures and Commentary (2013)." The previous version of RG 1.199 endorsed ACI 349-1997. It also endorses ACI 355.2-07, "Qualification of Post-Installed Mechanical Anchors in Concrete and Commentary," and ASTM E488-15, "Standard Test Methods for Strength of Anchors in Concrete Elements."
