Abstract
This study presents a theoretical investigation on retrofitting AASHTO prestressed bridge-girder, type PCB-5, using Carbon Fiber Reinforced Polymer (CFRP) to increase flexural strength. CFRP has been mainly used to strengthen the tension regions only Herish and Razzaq showed that installing CFRP in both tension and compression regions of building prestressed concrete inverted tee beams [4] and bridge box girders [5] increases flexural strength and decreases mid-span deflection.
