Abstract:This paper deals with a laboratory study to investigate the flexural behavior of full-scale damaged prestressed concrete (PC) bridge girders upgraded with externally bonded carbon fiber-reinforced polymer (CFRP) laminates. The experiments described in the paper concern tests on three beams: one was used as the control beam and the other two, damaged by removing the concrete cover and by cutting two and four strands, respectively, were repaired with CFRP laminates. Analytical predictions compared to tests resul… Show more
