A Methodology to Estimate Site-Specific Seismic Hazard for Critical Facilities on Soil or Soft-Rock Sites

Site-specific probabilistic seismic hazard assessments (PSHAs) and associated seismic design bases are critically dependent upon the local geological and geotechnical model. For reactor and critical non-reactor facilities on soil or softrock sites exhibiting strain-dependent behavior, estimates of site response can change significantly as site measurements and inferred structure evolve.
