Content:
f seismic responses for major Category I structures using modal response spectrum and time history approaches is evaluated. 13. Analysis Procedure for Damping The analysis procedure to account for the damping in different elements of the model of a coupled system is reviewed. 14. Determination of Category I Structure Overturning Moments The description of the method and procedure used to determine design overturning moments for Category I structures is reviewed. 15. Interface Review Review of geological and seismological information to establish the free- field ground motion is performed as described in SRP Sections 2.5.1 through 2.5.3. The geotechnical parameters and methods employed in the analysis of free-field soil media and soil properties are reviewed as described in SRP Section 2.5.4. The results of the reviews for the 3.7.2-4 Rev. 2 - August 1989 J % operating basis earthquake (OBE) and the safe shutdown earthquake (SSE), soil properties, etc., are used as an integral part of the seismic analysis review of Category I structures. For those areas of review identified above as being part of other SRP sections, the acceptance criteria necessary for the review and their methods of application are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA The acceptance criteria for the areas of review described in subsection I of this SRP section are given below. Other approaches that can be justified to be equivalent to or more conservative than the stated acceptance criteria may be used. The staff accepts the design of structures, systems, and components that are important to safety and must withstand the effects of earthquakes if the relevant requirements of General Design Criterion (GDC) 2 contained in Appendix A to 10 CFR Part 50 (Ref. 1) and Appendix A to 10 CFR Part 100 (Ref. 2) concerning natural phenomena are complied with. The relevant requirements of GDC 2 and Appendix A to 10 CFR Part 100 are: 1. General Design Criterion 2 - The design basis
