This is the twenty-ninth volume in the Earthquake Engineering Research Institute's series, Connections: The EERI Oral History Series. EERI began this series to preserve the recollections of some of those who have had pioneering careers in the field of earthquake engineering. Significant, even revolutionary, changes have occurred in earthquake engineering since individuals first began thinking in modern, scientific ways about how to protect construction and society from earthquakes. The Connections series helps document this important history. This volume in the EERI Oral History Series presents the life and career of Anil K. Chopra, Professor Emeritus in the Department of Civil and Environmental Engineering at the University of California, Berkeley. After he graduated from college in India, he went to UC Berkeley to earn his Master's and PhD degrees, then taught at the University of Minnesota before returning to join the faculty of UC Berkeley for the next 47 years, retiring in 2016. The first class he was asked to teach at UC Berkeley was structural dynamics, a course which had been started by his mentors, Ray Clough and Joe Penzien. His work in that field resulted in a number of publications on a wide range of topics in earthquake engineering and structural dynamics. Chopra chaired the structural analysis committee of the project producing the influential ATC-3, Tentative Provisions for the Development of Seismic Regulations for Buildings, and he tells interesting stories about working with Nate Newmark, Emilio Rosenblueth, Henry Degenkolb, and others. His expertise in structural dynamics resulted in his being asked to write the EERI monograph on structural dynamics, Dynamics of Structures: A Primer, and later led to his very widely used university textbook, Dynamics of Structures: Theory and Application to Earthquake Engineering, now in its fifth edition. A major theme in Chopra's research is the seismic analysis and design of concrete dams. He and a number of PhD students developed procedures for earthquake analysis of concrete dams, and he has consulted on dozens of major projects around the world. In 2020 he published his comprehensive book on the subject, Earthquake Engineering for Concrete Dams: Analysis, Design, and Evaluation.

Elastomeric bridge bearings have been used by various states in the mid-America region to accommodate thermal movement of bridge decks for over thirty years. Their potential role for mitigating damage in the infrequent but high consequence earthquakes that characterize the central United States is explored in this project. The potential protective role of conventional elastomeric bearings is critically influenced by material properties such as shear modulus, known to be temperature dependent. The degree of influence at low temperatures is determined through experimental studies. Slip characteristics of in-service aged and contaminated Teflon interfaces are determined. Full-scale bearings taken from existing bridges in addition to new bearings form the basis of these tests. Materials tests performed on the elastomer characterize the properties of aged bearings. The influence of these physical properties on possible bridge damage caused by earthquake ground shaking is assessed through computational simulations. A retrofit bearing with improved details for seismic isolation is designed and tested. An apparatus for testing the bearings was developed to simulate actual loading conditions. The apparatus provides a temperature-controlled chamber to allow for low temperature testing. Test protocols are developed to address the influence of testing parameters such as low temperature exposure and compressive stress. The prototype retrofit bearing design was also tested in this setup. The seismic response of a representative bridge is assessed by computational simulations conducted using the nonlinear analysis software DRAIN-2DX.

The Rapid Visual Screening (RVS) handbook can be used by trained personnel to identify, inventory, and screen buildings that are potentially seismically vulnerable. The RVS procedure comprises a method and several forms that help users to quickly identify, inventory, and score buildings according to their risk of collapse if hit by major earthquakes. The RVS handbook describes how to identify the structural type and key weakness characteristics, how to complete the screening forms, and how to manage a successful RVS program.

Maintenance, Safety, Risk, Management and Life-Cycle Performance of Bridges contains lectures and papers presented at the Ninth International Conference on Bridge Maintenance, Safety and Management (IABMAS 2018), held in Melbourne, Australia, 9-13 July 2018. This volume consists of a book of extended abstracts and a USB card containing the full papers of 393 contributions presented at IABMAS 2018, including the T.Y. Lin Lecture, 10 Keynote Lectures, and 382 technical papers from 40 countries. The contributions presented at IABMAS 2018 deal with the state of the art as well as emerging concepts and innovative applications related to the main aspects of bridge maintenance, safety, risk, management and life-cycle performance. Major topics include: new design methods, bridge codes, heavy vehicle and load models, bridge management systems, prediction of future traffic models, service life prediction, residual service life, sustainability and life-cycle assessments, maintenance strategies, bridge diagnostics, health monitoring, non-destructive testing, field testing, safety and serviceability, assessment and evaluation, damage identification, deterioration modelling, repair and retrofitting strategies, bridge reliability, fatigue and corrosion, extreme loads, advanced experimental simulations, and advanced computer simulations, among others. This volume provides both an up-to-date overview of the field of bridge engineering and significant contributions to the process of more rational decision-making on bridge maintenance, safety, risk, management and life-cycle performance of bridges for the purpose of enhancing the welfare of society. The Editors hope that these Proceedings will serve as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers and engineers from all areas of bridge engineering.

The Loma Prieta earthquake struck the San Francisco area on October 17, 1989, causing 63 deaths and $10 billion worth of damage. This book reviews existing research on the Loma Prieta quake and draws from it practical lessons that could be applied to other earthquake-prone areas of the country. The volume contains seven keynote papers presented at a symposium on the earthquake and includes an overview written by the committee offering recommendations to improve seismic safety and earthquake awareness in parts of the country susceptible to earthquakes.
