Development of Site Amplification Factors for Reference Outcrop Site Conditions in the State of South Carolina
This study develops site amplification factors for “reference outcrop” site conditions relative to hard rock in the Blue Ridge/Piedmont and Coastal Plain regions of South Carolina. In order to develop the site amplification factors, probabilistic site response analyses were performed considering random (i.e., aleatory) variability and epistemic uncertainty in the subsurface stratigraphy (both material type and thickness of layers), shear-wave velocity profiles, shear-modulus reduction curves, and material damping ratio curves. The results of the probabilistic site response analyses are presented in terms of median site amplification factors and the associated total (i.e., aleatory plus epistemic) standard deviation in natural log units for reference outcrop site conditions for horizontal peak ground acceleration (PGA) and 17 spectral periods. The site amplification factors were used to develop seismic hazard maps for the reference outcrop site conditions. This study is part of an effort to develop statewide seismic ground motion hazard maps for the South Carolina Department of Transportation.
