• Abstract:
  Shortly after the 1994 Northridge Earthquake, Caltrans geotechnical engineers charged with developing site-specific ; response spectra for high priority California bridges initiated a research project aimed at broadening their perspective ; from simple geotechnical site response analyses to a more comprehensive seismological approach. The project was ; centered on a series of seminars on seismological theory and analyses using a pair of stochastic numerical ground ; motion models that allowed uniform treatment of uncertainties in recognized earthquake source, path, and site effects. ; The project was not intended to produce a “report” per se, but rather, was meant to strengthen the knowledge and ; perspective of practicing engineers. Nevertheless, hard copy of seminar notes and a portion of the analyses have now ; been recovered, scanned and compiled into this volume for their archival and educational value. ; Seven sets of seminar notes and two application examples are presented. Two seminars provide an overview of sitespecific ; specification of ground motion from a seismological perspective. Another seminar provides background on ; seismological instrumentation and processing of strong-motion recordings. A pair of seminars addresses empirical ; attenuation models and outlines the variety of numerical ground motion modeling approaches. The final pair of seminars ; systematically explore source, path and site effects on ground motion and various strategies employed to capture these ; effects for purposes of prediction. The two application examples use the stochastic model to explore the impacts and ; uncertainties of geotechnical site effects within the context of the broader seismological problem.
