Evaluating Long Term Capacity & Ductility and the Design of Highway Bridges

Design criteria of bridge beams prestressed with carbon fiber reinforced polymer (CFRP) strands are established in a report from the Michigan Department of Transportation. This report evaluates CFRP design parameters such as maximum tensile strength, guaranteed strength, environmental reduction factors, relaxation, creep rupture strength, short and long-term prestress loss, and performance at elevated temperatures.
