Engineering Characterization of Ground Motion. Task 2. Observational Data on Spatial Variations of Earthquake Ground Motion.

摘要

The report presents the results of part of a two-task study on the engineering characterization of earthquake ground motion for nuclear power plant design. Task I of the study, which is presented in NUREG/CR-3805, Vol. 1, developed a basis for selecting design response spectra taking into account the characteristics of free-field ground motion found to be significant in causing structural damage. Task II incorporates additional considerations of effects of spatial variations of ground motion and soil-structure interaction on foundation motions and structural response.
