Evaluation and Implementation of an Improved Methodology for Earthquake Ground Response Analysis: Uniform Treatment of Uncertainties in Source, Path, and Site Effects. Final Reports

摘要

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.
