Content:
in accordance with the ACI-349 Code, as augmented by Regulatory Guide 1.142. c. For Category I steel foundations, the procedures are in accordance with the AISC N690 "Specifications...". 42 d. For the containment foundation, the design and analysis procedures referenced in subsection II.4 of SRP Section 3.8.1 are acceptable. e. The design report is found acceptable if it satisfies the guidelines contained in Appendix C to SRP Section 3.8.4. f. The structural audit is conducted as described in Appendix B to SRP Section 3.8.4. For determining the overturning moment due to an earthquake, the three components of the earthquake should be combined in accordance with methods described in SRP Section 3.7.2. 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. 5. Structural Acceptance Criteria For each of the loading combinations referenced in subsection II.3 of this SRP section, the allowable limits which constitute the acceptance criteria are referenced in subsection II.5 of SRP Section 3.8.1 for the containment foundation and are listed in subsection II.5 of SRP Section 3.8.4 for all other foundations. In addition, for the fivefour additionalother load combinations delineated in subsection II.3 of this SRP 43 section, the factors of safety against overturning, sliding, and flotation are acceptable if found in accordance with the following: Minimum Factors of Safety For Combination Overturning Sliding Flotation a. ----------------------- 1.5 1.5 b. ----------------------- 1.5 1.5 --- 3.8.5-9 DRAFT Rev. 2 - April 1996 c. ----------------------- 1.1 1.1 --- d. ----------------------- 1.1 1.1 --- e. ---------------------- --- --- 1.1 6.
