Instructor Dr. Praveen K. Malhotra Dr. Praveen Malhotra is a Senior Research Scientist with FM Global Research in Norwood, MA. He has over 15 years of research, practical, and teaching experience in various aspects of earthquake engineering. For the last 5 years, his research has been focused on the loss prevention and loss estimation aspects of earthquake ground shaking. For 7 years prior to that, he measured and analyzed seismic records from structures and ground stations throughout California. He has taught graduate, undergraduate, and continuing education courses in earthquake engineering, soil, and structural dynamics. He has more than 25 papers published in peer-reviewed journals and has made invited presentations throughout USA, South Korea, Switzerland, and India. He has been a member of teams sent out to collect scientific data following earthquakes. Dr. Malhotra has a Ph.D. in structural engineering, with emphasis on earthquake engineering, from Rice University. He is a member of the American Society of Civil Engineers (ASCE), Earthquake Engineering Research Institute (EERI), Seismological Society of America (SSA), and the Indian Society of Earthquake Technology (ISET). He serves on national committees dealing with seismic issues. He peer-reviews research articles submitted to various journals, and research proposals submitted for funding to various agencies. He is a registered Civil Engineer (P.E.) in California. Back to Top

Course Description This seminar presents a step-by-step evaluation of ground motions for design and assessment of structures for seismic loads. The evaluation of site-specific ground motions requires an interaction between geology, seismology, geotechnical engineering, and structural engineering. Professionals in any of these fields possess some knowledge of the related fields, but, invariably gaps are left in this knowledge. This seminar is aimed at closing those gaps through an intuitive approach. The seminar is divided into 6 parts, each aimed at answering a few key questions: Basic geology and seismology: Why earthquakes happen? Where will future earthquakes occur? What will be the size and frequency of future earthquakes? Ground motions from past earthquakes: How the ground motions are measured? Which characteristics of ground motions are most significant for engineering analyses? What are the key parameters to capture these characteristics? Ground motions for future earthquakes: How are the ground motion prediction relationships derived from the prerecorded seismic data? How are these relationships used to estimate ground motions for future earthquakes? How are the ground motion hazard maps in building codes generated? Effect of local geology on ground motions: How do the local soil conditions affect the ground motions at a site? How are these effects quantified? Near-source effects on ground motions: What are the special characteristics of ground motions in close proximity of major seismic sources? How do they affect the response of structures? Soil-structure interaction: How does the presence of a structure influence the ground motion at a site? Back to Top Seminar Benefits Learn about the ground motion characteristics  which influence the dynamic response of structures Learn to perform site-specific seismic hazard calculations using deterministic and probabilistic analyses Learn how to select and modify ground motion histories for dynamic analyses Obtain information on the sources of ground motion data Gain insight into the effects of local soil conditions on ground motion characteristics Learn background information regarding the ground motion provisions in UBC, NEHRP, ASCE7, IBC and NFPA 5000 Learn the difference between hazard and risk Back to Top Who Should Attend Structural engineers, geotechnical engineers, geologists, architects, building officials, and professionals in related fields who are interested in consolidating and widening their knowledge of earthquake ground motions, and their effects on structures and soil deposits.

The course was comprehensive; included from basics of seismology to ground motions fundamentals to site specific response analysis. The instructor did a great job presenting a complex topic.” -J. Alan Goble, M.S., P.E., Senior Geotechnical Engineer Bowser-Morner Associates, Lexington, KY “A very comprehensive explanation of earthquake includes ground motion and the effects on sites. The course provided the fundamentals for site calculations and analysis.” -R.Hayne Palmer, United Consulting, Norcross, GA “A very good introduction to seismic theory and practice giving insight and understanding to the concepts mandated in the building codes. Insight into practical explanations and logic behind the building codes requirement was very helpful.” -Timothy C. Ish, P.E., Director of Engineering Taylor Engineering Inc., Jacksonville, FL “Best two-day CEUs earning seminar I have attended.” John McConaghy,Duke Energy,Charlotte,NC “The instructor had an excellent command of the subject and was very open to questions. The subject matter was presented in a manner which built an understanding of the basic and background issues prior to presenting analysis method.” -Daniel B.Bunnell, Bunnell-Lammuius Engineering ,Greenville, SC Back to Top
