accordance with the acceptance criteria of subsec- tion II.2.f of this SRP section. Typical mathematical models are reviewed to judge whether all significant degrees of freedom have been included. g. Multiply-Supported Equipment and Components With Distinct Inputs The criteria for the seismic analysis of multiply-supported com- ponents and equipment with distinct inputs are reviewed to determine that the criteria are in accordance with the -acceptance criteria of subsection II.2.g of this SRP section. h. Use of Constant Vertical Static Factors Use of constant static factors as response loads in the vertical direction for the seismic design of any Category I systems 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 ver- tical direction based on the definition for rigidity given in subsection II.2.h of this SRP section. i. Torsional Effects of Eccentric Masses The procedures for seismic analysis of Category I piping systems are reviewed to determine compliance with the acceptance criteria of subsection II.2.i of this SRP section. j. Category I Buried Piping Systems The analysis procedures for Category I buried piping are reviewed to determine that they are in accordance with the acceptance criteria of subsection II.2.j of this SRP section. This includes review of the procedures used to consider the effect of fill settlement includ- ing pipe profile and pipe stresses, and the differential movements at support points, penetrations, and anchors. Any procedures that are not adequately justified are so identified and the applicant is requested to provide additional justification. 3. 9.2-17 Rev. 2 - July 1981 k. Interaction of Other Piping with Category I Piping The criteria used to design the interfaces between Category I and non-Category I piping are reviewed to determine compliance with the acceptance criteria of subsection II.2.k of this SRP section. 1. Criteria used for Damping The
