s for Nuclear Safety-Related Concrete Structures (ACI 349-13) and Commentary” (Ref. 26), Appendix D, and all other references to ACI 318 should be replaced with ACI 349-13. In addition, requirements in ACI 349-13 should be used along with the regulatory positions in RG 1.142, Revision 3, and RG 1.199, Revision 2, unless otherwise justified. 6. ANSI/AISC N690-18, Chapter NN—Quality Control and Quality Assurance RG 1.28 should be used for QA in design, construction, inspection, and testing of steel and composite structures covered by this RG. 7. ANSI/AISC N690-18, Appendix N1—Design by Advanced Analysis ANSI/AISC N690-18, Appendix N1, on design by advanced analysis, incorporates AISC 360-16, Appendix 1, with certain modifications. The following qualifications apply to Appendix N1: 7.1. Nonlinear inelastic analysis, in accordance with ANSI/AISC N690-18, Section NB3.14, is acceptable to treat impactive and impulsive loads. DG-1304. Page 11 7.2. Nonlinear inelastic analysis, in accordance with ANSI/AISC N690-18, Appendix N1, Section 1.3.1 supplement to AISC 360-16, Appendix 1, Section 1.3.1, is acceptable to treat thermally induced local inelastic effects. 7.3. Nonlinear inelastic analysis, in accordance with AISC 360-16, Appendix 1, Section 1.3, is acceptable for the structural evaluation of seismic Category II (nonsafety related) steel structures to address seismic Category II/I interactions. The NRC staff reviews the details of each analysis. 7.4. Nonlinear elastic analysis, in accordance with AISC 360-16, Appendix 1, Section 1.2, is acceptable for use with AISC 360-16, Chapter C, for an elastic stability analysis of safety-related steel building structures if stresses are below the elastic limit at the onset of instability. 7.5. Nonlinear inelastic analysis, in accordance with AISC 360-16, Appendix 1, Section 1.3, is acceptable for use with AISC 360-16, Chapter C, for an inelastic stability analysis of safety-related steel building structures if stresses exceed
