to account for damping in different elements of the model of a coupled system is reviewed to determine that it is in accordance with the acceptance criteria of SRP Section 3.7.2, subsection II.13. 6. Three Components of Earthquake Motion The procedures by which the three components of earthquake motion are considered in determining the seismic response of subsystems are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection II.6. 7. Combination of Modal Responses The procedures for combining modal responses are reviewed to determine compliance with the acceptance criteria of SRP Section 3.7.2, subsection II.7 when a response spectrum modal analysis method is used. 8. Interaction of Other Systems with Category I Systems The criteria used to design the interfaces between Category I and non-Category I systems are reviewed to determine compliance with the acceptance criteria of subsection II.8 of this SRP section. DRAFT Rev. 3 - April 1996 3.7.3-10 9. Multiply-Supported Equipment and Components With Distinct Inputs The criteria for the seismic analysis of multiply-supported equipment and components with distinct inputs are reviewed to determine that the criteria are in accordance with the acceptance criteria of subsection II.9 of this SRP section. 10. Use of Equivalent Vertical Static Factors Use of equivalent static factors as response loads in the vertical direction for the seismic design of any Category I subsystems in lieu of a detailed dynamic method is reviewed to determine that constant static factors are used only if the structure is rigid in the vertical direction. 11. Torsional Effects of Eccentric Masses The procedures for seismic analysis of Category I subsystems are reviewed to determine compliance with the acceptance criteria of subsection II.11 of this SRP section. 12. Category I Buried Piping, Conduits, and Tunnels The analysis procedures for Category I buried piping, conduits, tunnels, and auxiliary systems are
