Instructors:
Dr. Gonzalo Castro, GEI Consultants Inc., Boston
He is a geotechnical engineer with over 45 years of experience in the practice of geotechnical engineering. Dr. Castro’s professional experience has been primarily as the engineer in charge of the geotechnical aspects of major civil engineering projects as a principal of GEI Consultants. His contributions to the practice of geotechnical engineering have been principally in the understanding of the behavior of soils during earthquakes and its application to the seismic safety of dams. Elected to the National Academy of Engineering for contributions to geotechnical earthquake engineering, soil dynamics and the seismic safety of dams, Dr. Castro is also a Fellow of the American Society of Civil Engineers (ASCE), and Honorary Member of the Boston Society of Civil Engineers. He received his doctorate in Soil Mechanics at Harvard University and specializes in the behavior of soils during earthquakes.
Professor Ahmed Elgamal, University of California, San Diego
Since 1997, Prof. Elgamal (PhD 1984, Princeton University) has been serving as Professor of Geotechnical Engineering at the University of California, San Diego (UCSD). Earlier, he held academic appointments at the California Institute of Technology (Post Doctor and Lecturer, Pasadena, CA), Rensselaer Polytechnic Institute (Assistant and Associate Professor and Technical Director of RPI Centrifuge Testing Facility, Troy, NY), and Columbia University (Associate Professor, New York, NY). He Chaired the UCSD Department of Structural Engineering from 2003 to 2007. Professor Elgamal’s research has been focused on seismic experimental and computational analysis and modeling of geotechnical and SSI systems (site response, liquefaction and mitigation, earth and rockfill dams). In his published studies, he developed/ employed data sets from centrifuge and large-scale shake table testing, and earthquake downhole geotechnical arrays worldwide. Based on this experimentation background, he has developed nonlinear computational analysis techniques that are now available via the open-source computational framework (e.g., http://opensees.berkeley.edu, http://cyclic.ucsd.edu, http://cyclic.ucsd.edu/openseespl). He is author and co-author of over 250 publications.
Dr. Jorge Meneses, GEI Consultants Inc., Carlsbad
Jorge Meneses has more than 25 years of experience in geotechnical engineering with emphases on geotechnical earthquake engineering, foundation engineering, numerical modeling, and advanced geotechnical testing. His experience includes consultancy for major companies, and research and teaching in major universities in the U.S., Japan, and Peru. Jorge has published about 60 technical publications in technical journals and conferences, is a frequent peer reviewer of journal and conferences papers, and has been invited as a guest speaker for national and international conferences. His expertise includes probabilistic and deterministic seismic hazard evaluation, liquefaction and lateral spread analysis, numerical modeling of dynamic behavior of earth works, seismic soil-structure interaction, seismic design of foundations, shallow and deep foundation design, site response and site characterization, seismic slope stability, and development of earthquake ground motion for dynamic analyses. He is a part-time lecturer in the Graduate School of San Diego State University, and University of California, San Diego Extension. Jorge is the founder and current president of the EERI San Diego Chapter. Jorge is a Diplomate, Geotechnical Engineer, member of the Academy of Geo-Professionals, and is a Fellow of the American Society of Civil Engineers.

January Joint Dinner Meeting with EERI
10 Years of Research Achievement of the NEES-UC San Diego Shaking Table
In this presentation, Prof. Jose Restrepo will highlight the 10 years of research achievement of the NEES-UC San Diego Shaking Table. Numerous landmark research projects have been carried out on the shaking table, resulting in discovering of new knowledge and advancement of design codes. In particular, Prof. Restrepo will highlight the research project on thin structural walls, and will contrast its main findings with observations made in the M8.8 Chile earthquake. He will also show the research project on precast concrete diaphragms and will briefly discuss the main changes to ASCE 7 that this research work brought up. Furhtermore, Prof. Restrepo will highlight the main findings of the research project on a fully equipped 5-story building, which was tested with base-isolation and then and then in a fixed-based condition. Prof. Restrepo will end its presentation with a brief discussion of a building project whose design aims at reducing floor inertia forces. This building is being currently tested on the NEES-UC San Diego shake table.
Jose. Restrepo is a Professor in Structural Engineering at the University of California, San Diego. Professor Restrepo research interests are in earthquake engineering and structural dynamics, with emphasis in structural design and experimental methods. Professor Restrepo was lead structural engineer for the NEES UC San Diego Large High-Performance Outdoor Shake Table, the largest in the United States and second largest worldwide. There he has leader or collaborator for a number of landmark experiments performed on this shake table. Prof. Restrepo’s research has been recognized with the ACI Chester Paul Siess Award, the PCI Charles C. Zollman and Martin Korn Awards, the FHWA James Cooper Award and the ASCE Alfred Noble Award.
