Gergis William, Ph.D., P.E., F.SEI, F. ASCE
Senior Structural Engineer at AECOM and Adjunct Associate Professor at West Virginia University
Dr. William is a professional structural engineer with over 25 years of academic and consulting experience in the structural analysis, design, long-term monitoring, and condition assessment of highway bridges and pavement structures. His experience has also extended to the design and construction of waterfront structures, as well as industrial and high-rise residential buildings. Dr. William has published over 120 articles in international journals and conference proceedings. He is a member of
several national technical committees and has participated in writing four design codes/guidelines published by the American Concrete Institute. Dr. William has extensive experience with 3D nonlinear finite element analysis of diverse complex structures using LS-DYNA. He has dealt with problems involving mesh construction of complicated geometries, contact, nonlinear material behavior, fracture and failure analysis, and validating results with experimentally measured data. He has experience with lightweight composite structures with an emphasis on automotive light-weighting technologies and lightweight dense hydrogen storage systems. He has also worked on the structural characterization of lightweight composite materials including polymer-reinforced composites and metal matrix composites. Starting his career as a structural/geotechnical engineer, followed by long experience with long-term field monitoring of the performance of various types of bridges, Dr. William has been exposed to many problems associated with bridge construction and design specifications such as early age full-depth longitudinal cracks in empirically designed bridge decks, transverse deck cracking, out-of-plane web distortion of steel I-girders, and restrained bridge expansion at integral abutment or expansion joints. Dr. William has provided expert assistance in several issues such as early age longitudinal cracking of empirically designed bridge decks and out-of-plane distortion of steel girders through WVDOT/FHWA task force in 2006-2007.
