Development of site-specific earthquake response spectra for eastern US sites.

摘要

Site-specific earthquake, uniform-hazard response spectra have been defined for the Department of Energy Oak Ridge, Tennessee, and Portsmouth, Ohio, sites for use in evaluating existing facilities and designing new facilities. The site-specific response spectra were defined from probabilistic and deterministic seismic hazard studies following the requirements in DOE-STD-1024-92, ''Guidelines for Probabilistic Seismic Hazard Curves at DOE Sites.' For these two sites, the results show that site-specific uniform-hazard response spectra are slightly higher in the high-frequency range and considerably lower in the low-frequency range compared with response spectra defined for these sites in the past.
