tions are reviewed with respect to the applicability of the theories on which these procedures are based. Among the areas reviewed are the following: a. The assumptions made on boundary conditions and the expected behavior of each foundation when subjected to the various design loads. b. The methods by which lateral loads and forces and overturning moments thereof are transmitted from the structure to the foundation media. Such forces are mainly generated by the environmental and abnormal plant conditions such as wind, tornadoes, earthquakes, and pipe ruptures. Methods of determining overturning moments due to the three components of the earthquake are also reviewed. DRAFT Rev. 2 - April 1996 3.8.5-4 c. The computer programs that are used in the design and analysis of seismic Category I foundations. d. A Category I structures design report is reviewed (Appendix C, SRP Section 3.8.4). e. A structural audit is conducted (Appendix B, SRP Section 3.8.4). 5. Structural Acceptance Criteria The foundation, as a connecting line between the structure and soil media, is reviewed for its capability ofto receivinge and transmitting loads within appropriate safety margins.5 The design limits imposed on the various parameters that serve to quantify the structural behavior of each foundation are reviewed with emphasis on the extent of compliance with the ACI-349 Code for concrete structures, specifically with respect to stresses, strains, and deformations. Factors of safety against overturning and sliding are reviewed for their appropriate safety margins. 6. Materials, Quality Control, and Special Construction Techniques Information on the materials used in the construction of seismic Category I foundations is reviewed. Among the major materials of construction reviewed are the following: a. The concrete ingredients. 6 b. The reinforcing bars and mechanical splices. c. The structural steel. d. Rock anchors, including any prestressing system. The quality control program proposed
