Draft Revision 4 - December 2012 floor response spectra (e.g., peak width) and to determine compliance with the acceptance criteria of subsection II.9 of this SRP section. Among the various structural parameters analyzed, the effect of potential concrete cracking on structural stiffness should be addressed. 10. Use of Equivalent Vertical Static Factors. Use of constant static factors as response loads in the vertical direction for the seismic design of any Category I SSC, in lieu of a detailed dynamic method, is reviewed to determine compliance with the acceptance criteria of subsection II.10 of this SRP section. 11. Methods Used to Account for Torsional Effects. The methods of seismic analysis are reviewed to determine that the torsional effects of vibration are incorporated, in compliance with the acceptance criteria of subsection II.11 of the SRP section. Justification provided by the applicant for the use of any approximate method to account for torsional effects is reviewed, to ensure that it results in a conservative design. 12. Comparison of Responses. Where applicable, the responses obtained from both time history and response spectrum methods at selected points in major Category I structures are compared to judge the accuracy of the analyses conducted. The applicant should explain any significant discrepancies in the results of the two methods. 13. Analysis Procedure for Damping. The analysis procedure to account for differences in damping in different elements of the system structural model is reviewed to determine that it is in accordance with the acceptance criteria of subsection II.13 of this SRP section. 14. Determination of Seismic Overturning Moments and Sliding Forces for Category I Structures. The analysis methods to calculate seismic overturning moments and sliding forces are reviewed to determine compliance with the acceptance criteria of subsection II.14 of this SRP section. 15. Design Certification and Combined License Reviews. For review of a
