0.9, if it can be demonstrated that the load is always present or occurs simultaneously with other loads. Otherwise, the coefficient for that load should be taken as zero. Where the structural effect of differential settlement may be significant, it should be included with the dead load, D. 4. Design and Analysis Procedures The design and analysis procedures utilized for Category I structures, including assumptions on boundary conditions and expected behavior under loads, are acceptable if found in accordance with the following: a. For concrete structures, the procedures are in accordance with ACI-349, "Code Requirements for Nuclear Safety Related Structures," (Ref. 1) supplemented by 54 Regulatory Guide 1.142 and Appendix E to this SRP section.55 b. For steel structures, the procedures are in accordance with the AISC "Specification..."ANSI/AISC N690-1984, supplemented by Appendix F to this SRP section (Ref. 3). 56 57 c. Computer programs are acceptable if the validation provided is found in accordance with procedures delineated in subsection II.4.e of SRP Section 3.8.1. 3.8.4-15 DRAFT Rev. 2 - April 1996 d. Design report is considered acceptable if it contains the information specified in Appendix C to this SRP section. e. Structural audit is conducted in accordance with the provisions of Appendix B to this SRP section. f. Design of spent fuel pool and rods is considered acceptable when the requirements of Appendix D to this SRP section are met. g. Consideration of dynamic lateral soil pressures on earth retaining walls and embedded walls is acceptable when the requirements of Appendix G to this SRP section are met.58 h. Design of masonry walls is considered acceptable when the requirements of Appendix A are met. 59 5. Structural Acceptance Criteria For each of the loading combinations delineated in subsection II.3 of this SRP section, the following defines the allowable limits which constitute the structural acceptance criteria: a. In Combinations for Concrete
