Dr. Jorge Meneses is Principal Geotechnical Engineer with RMA Group. He is a member of the California Seismic Safety Commission appointed by Governor Brown and confirmed by the State Senate. He is a reviewer of seismic ground motions for the seismic design of high rise buildings for the City of San Diego, part-time faculty at San Diego State University, Fellow of the American Society of Civil Engineers (ASCE), member of the Industry Advisory Board of the Department of Structural Engineering at University of California San Diego, member of the Board of Directors of the Earthquake Engineering Research Institute (EERI), President of the EERI San Diego Chapter, past Member of the ASCE 7-16 Committee (Minimum Design Loads for Buildings and Other Structures), member of the ASCE 1 Committee (Geotechnical Analysis, Design, Construction, Inspection and Monitoring of Nuclear Safety-Related Structures), Honorary Chair of the ASCE Geo-Institute San Diego Chapter, and member of the Academy of Geo-Professionals. He is an expert in geotechnical, foundation, and earthquake engineering. His areas of expertise include probabilistic and deterministic seismic hazard analysis, seismic deaggregation, selection and modification of earthquake ground motions, site response and characterization, liquefaction and lateral spread evaluation and mitigation, seismic stability of earthworks, post- earthquake reconnaissance, numerical modeling and advanced geotechnical testing. Dr. Meneses specializes in seismic soil- structure interaction analysis, and analysis and design of pile foundations subjected to liquefaction and lateral spread. He has experience with seismic hazard evaluation and ground motions development in different seismotectonic environments, and has in-depth knowledge of seismic regulations for dams, buildings, bridges, nuclear facilities, ports, and others. Dr. Meneses has professional experience in the United States, Japan, Peru, India, and Mexico. He has been involved in numerous projects serving as a technical lead in earthquake geotechnical engineering and foundation engineering across the country. Dr. Meneses frequently acts as a peer reviewer for technical conferences and technical journal publications, is a guest speaker for domestic and international conferences, and has published more than 60 technical publications.
One of the seismic analysis and design procedures of seismically isolated structures and structures with damping includes the performance of dynamic time-history analysis of the structure. This procedure requires the development of different input motions or seismic ground motions that will be applied to the structure. The current ASCE 7-16 seismic provisions provide the guidance for developing these seismic ground motions.
After an overview of ground motion characteristics especially in the near-field and some general considerations of site-specific seismic hazard evaluation, some general information will be provided on time histories databases, and modification procedures. Then, the ASCE 7-16 procedures for developing the MCER ground motions for seismically isolated structures, and Design and MCER ground motions for structures with damping systems will be presented and discussed.
