1Amir Fam, who grew up in Alexandria, Egypt, says he was always fascinated by freehand art, architecture, and structures, including architectural renderings. He completed a five-year bachelor's degree in civil engineering at Alexandria University in 1991 and then completed research master's and doctoral degrees at the University of Manitoba in Winnipeg, Canada, in 1997 and 2000, respectively. He then spent two years as a postdoctoral fellow and instructor at North Carolina State University in Raleigh before starting his tenure-track academic career in 2002 at Queen's University in Kingston, ON, Canada. Like many, coincidence led him to a profession in the precast concrete industry. "My passion for structures and architecture came together, and the right opportunity came my way," he says. "My master's degree, and then doctoral degree, under the supervision of Professor Sami Rizkalla, a prominent and leading researcher in precast and prestressed concrete, opened the door for me to some incredibly unique and exciting opportunities." Fam's early research involved building and testing 30 ft (9.1 m) long one-third scale models of American Association of State Highway and Transportation Officials (AASHTO) girders for the first bridge ever built with pretensioned carbon-fiber-reinforced polymer (CFRP) strands harped at an angle and reinforced with CFRP stirrups, which are also used as shear connectors to the cast-in-place slab. |
