Abstract

This paper summarizes the deployment of fiber reinforced polymer (FRP) composites in the form of fabric, laminates, and rod panels over the past fifteen years on twenty eight reinforced concrete, prestressed concrete, and steel bridges throughout Kentucky. The field applications of FRP composites include: (1) retrofit of PC beams in shear using unidirectional carbon fabric; (2) flexural strengthening of concrete and steel beams using CFRP laminates; (3) retrofit of cracked ends of PC I-beams using carbon fabric; (4) retrofit of cracked PC box beams using carbon fabric; (5) retrofit of impacted PC beams with CFRP Rod Panels; (6) retrofit of cracked concrete pedestals using carbon fabric; and (7) retrofit of impacted concrete piers and pier caps using carbon fabric. This paper highlights eight case studies, each of which includes an in-depth discussion of the retrofit techniques used.
