Andrew P. Stam

Senior Associate


Andrew Stam has a diverse background in new design, evaluation, analysis, and research of structures. He is experienced in the design and assessment of various materials and systems, including steel, aluminum, reinforced concrete, prestressed concrete, masonry, and wood. He is proficient in advanced structural modeling techniques, including nonlinear finite element analysis. Mr. Stam applies his experience to solving structural problems, investigating damage and failures, and designing and detailing repairs. Before joining WJE, Mr. Stam worked for seven years as a design engineer with the Denver-based firm Martin/Martin, specializing in medium- to large-sized commercial, sports, and higher education projects. At the University of Texas, his broad-based research experience included projects in structural steel fatigue, blast loading of wall panels, and strut-and-tie modeling of reinforced concrete.
