Stewart, Ph.D., PE Department of Civil and Environmental Engineering University of California, Los Angeles A report on research conducted with support from the US Geological Survey, California Strong Motion Instrumentation Program, and Consortium of Organizations for Strong Motion Observation Systems Civil & Environmental Engineering Department University of California, Los Angeles December 2019 ABSTRACT This project was comprised of two distinct yet mutually beneficial tasks. The first was the establishment of a United States Community VS Profile Database (PDB). The second involved the use of that database to support ground motion studies that establish observation-based site response at ground motion recording stations and then seek to establish the degree to which it can be estimated using alternate prediction approaches. The development of the PDB has been, and continues as, a major multi-institutional effort to develop an open-access VS profile database for sites in the United States. The data described herein was collected from diverse sources that include consulting engineering reports from private industry, university research reports and other documents, federal open-file and similar reports, California state agency documents, and reports provided by electric utilities for selected sites. All data are strictly within the public domain, but much of it was for practical purposes inaccessible to most potential users.
