Seismic Analysis of Safety-Related Nuclear Structures and Commentary on Standard for Seismic Analysis of Safety Related Nuclear Structures

This standard provides requirements for performing analyses to obtain design information which will lead to the reliability of structures under a severe earthquake. The goal of this standard is to provide rules and analysis parameters that are expected to produce seismic design responses that have about a 90% chance of not being exceeded for a given design earthquke, assuming that the input response spectrum is specified at the mean plus one standard deviation level. Specification of input motions, response spectra and input motion time histories are covered. Analysis standards are given for modeling of structures, analysis of structures, soil-structure interaction modeling and analysis, input for subsystem seismic analysis, and special structures such as buried pipes and conduits, earth-retaining walls, and aboveground vertical tanks.
