Dr. Eric Sammarco joined Protection Engineering Consultants (PEC) in the fall of 2013 and has fourteen (14) years of structural engineering research and design experience. He currently serves as the company’s Advanced Technology + Research (AT+R) Team Leader and manages/supports projects and applied R&D efforts focused on risk mitigation for people, systems and mission-critical infrastructure from natural hazards, extreme accident scenarios, and hostile attacks. Eric’s technical interests include explosives safety site planning and protective design, assessment and design for blast, shock, and impact effects, application of advanced multi-physics modeling and simulation techniques, and application of performance-based analysis and design methodologies for natural and man-made hazards.

Since joining PEC, Eric has worked in several different industry sectors. He has supported licensing-basis and post-Fukushima plant modification projects and security-related assessment/upgrade projects for domestic and international nuclear power plants. He has performed multi-hazard assessments, seismic peer reviews, and seismic risk rating system development for commercial, U.S. military and heavy industrial clients. Eric has been heavily engaged in transportation infrastructure safety and security; key efforts have included primary authorship of the Federal Highway Administration’s (FHWA) Bridge Security Design Manual, chief developer of the Anti-Terrorism Planner for Bridges (ATP-Bridge) software for the Department of Homeland Security (DHS), applied research and development of stay-cable protection strategies for long-span bridges, vulnerability assessment of a highway bridge to the effects of ongoing quarry blasting, and Principal Investigator of a Phase 2 SBIR with the Federal Railroad Administration (FRA) aimed at enhancing rail passenger survivability during a derailment event through resilient wayside structure designs. Eric excels at employing high-fidelity numerical modeling techniques to enhance the accuracy of assessments and optimize risk mitigation strategies; examples include quantifying load effects from landmine detonations, assessments of industrial machines and equipment to accidental explosions, beyond-design-basis seismic capacity assessments, novel tornado missile barrier designs for nuclear plants, and the implementation of a statistical glass-fracture material model into a nonlinear dynamic finite element framework for predicting the blast response of architecturally complex glazed façade systems.
