Dr. Greg Mertz is a member of the Probabilistic Structural Mechanics Team, part of the Nuclear Design and Risk Analysis Group in the Decision Applications Division of Los Alamos National Laboratory.
Greg is a practical structural engineer with over 25 years of professional experience in analysis, design, and evaluation of structures, systems, and components. Before joining LANL, Greg worked at Westinghouse Savannah River Company (SRS) for 15 years in positions ranging from Senior Engineer to Manager of the Structural Engineering Group. At Savannah River, Greg performed structural analyses to support upgrading the safety basis of existing facilities and resolving operating problems. Greg also led a team of engineers through the structural analysis and design of the Tritium Extraction Facility at the SRS. Greg's steel design experience was gained while working for Butler Manufacturing Company.
Greg's specialties include linear and nonlinear structural analysis, structural dynamics (seismic, soil structure interaction, and impact), concrete and steel design, fracture mechanics, criteria development, and the resolution of structural problems to support the authorization basis. He has served as a consultant for structural projects across the DOE complex. Greg has presented and successfully defended numerous analyses to external review bodies, including the Defense Nuclear Facilities Safety Board. He is currently a structural peer reviewer for the Hanford Waste Treatment Plant design and the Idaho National Laboratory Advanced Test Reactor seismic reanalysis.
Greg is a licensed professional engineer in several states. He earned his Ph.D. at the University of Missouri-Rolla, where he developed hysteresis models and performed nonlinear dynamic analysis of low-rise reinforced concrete shear wall building systems.
