Local soil conditions can influence structural performance in two primary ways — by influencing the ground motions that excite the structure and by imposing additional deformations on the structure through ground failure. The first widespread observations of damage attributed to liquefaction were made in the 1964 Niigata, Japan, and 1964 Alaska earthquakes. In numerous earthquakes since, liquefaction has been deemed responsible for significant damage to buildings and bridges. Liquefaction has been studied extensively over the past 35 years, and substantial advances have been made in understanding the development and effects of this phenomenon. -
Shear Wave Velocity Database and Its Application for Analysis of Non-Ergodic Site Amplification Effects
Shear Wave Velocity Database and Its Application for Analysis of Non-Ergodic Site Amplification Effects Pengfei Wang Paolo Zimmaro, Ph.D. Department of Civil and Environmental Engineering University of California, Los Angeles Sean K. Ahdi, Ph.D. Exponent Los Angeles, CA Dong Youp Kwak, Ph.D. Hanyang University Ansan, South Korea Principal Investigator: Jonathan P. 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. -

Procedures for Estimating Earthquake Ground Motions
Procedures for Estimating Earthquake Ground Motions PROCEDURES FOR ESTIMATING EARTHQUAKE GROUND MOTIONS High-altitude view of the San Francisco Bay region showing surface traces of the Hayward and Calaveras faults. The Hayward fault was the source of two large earthquakes in 1836 and 1868 that caused surface rupture along as much as 64 km of its trace. The Calaveras fault, with a length of approximately 160 km, is one of the largest in northern California. The San Andreas fault passes offshore near Mussel Rock (arrow at bottom of photograph). Fault systems such as these must be critically studied when evaluating the seismic hazards and risk in an urban area. Procedures for Estimating Earthquake Ground Motions By WALTER W.
