Content:
the seismic response of systems are reviewed for compliance with the acceptance criteria of subsection II.2.D of this SRP section. E. Combination of Modal Responses. The procedures for combining modal responses are reviewed for compliance with the acceptance criteria of subsection II.2.E of this SRP section when a response spectrum modal analysis method is used. F. Analytical Procedures for Piping Systems. For all Seismic Category I piping and applicable non-Seismic Category I piping, the methods of seismic analysis (response spectra, time history, equivalent static load) are reviewed for techniques in accordance with the acceptance criteria of subsection II.2.F of this SRP section. Typical mathematical models are reviewed to judge whether all significant degrees of freedom have been included. G. Multiple-Supported Equipment and Components with Distinct Inputs. The criteria for the seismic analysis of multiple-supported components and equipment with distinct inputs are reviewed for accordance with the acceptance criteria of subsection II.2.F of this SRP section. 3.9.2-34 Revision 4 – March 2017 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 seismic Category I systems in lieu of a detailed dynamic method is reviewed for whether constant static factors are used only if the structure is rigid in the vertical direction based on the definition for rigidity in subsection II.2.G of this SRP section. I. Torsional Effects of Eccentric Masses. The procedures for seismic analysis of Seismic Category I piping systems are reviewed for compliance with the acceptance criteria of subsection II.2.I of this SRP section. J. Seismic Category I Buried Piping Systems. The analysis procedures for Seismic Category I buried piping are reviewed for accordance with the acceptance criteria of subsection II.2.J of this SRP section, including review of the procedures for considering the effect
