Abstract

One-hundred and ninety free-field accelerograms recorded on deep soil (>10 m deep) were used to study the near-source scaling characteristics of peak horizontal acceleration for 91 earthquakes (2.5 ??? ML ??? 5.0) located primarily in California. An analysis of residuals based on an additional 171 near-source accelerograms from 75 earthquakes indicated that accelerograms recorded in building basements sited on deep soil have 30 per cent lower acclerations, and that free-field accelerograms recorded on shallow soil (???10 m deep) have 82 per cent higher accelerations than free-field accelerograms recorded on deep soil. An analysis of residuals based on 27 selected strong-motion recordings from 19 earthquakes in Eastern North America indicated that near-source accelerations associated with frequencies less than about 25 Hz are consistent with predictions based on attenuation relationships derived from California. -from Author
