REHABILITATION OF DAMAGED AASHTO TYPE II PRESTRESSED GIRDER USING CFRP

Fiber reinforced polymers composites are finding many practical applications in the field of bridge rehabilitation. Presented in this paper are experimental results pertaining to the strengthening of an AASHTO type II prestressed concrete girder with Carbon Fiber Reinforced Polymer (CFRP) composites. The girder was initially tested to ultimate as part of a study on transfer length and bond of strands. In this study, tests were conducted to examine the stiffness and strength of the girder before and after being strengthened by the use of CFRP. Test results suggest that CFRP be used to partially restore the stiffness and increase the strength of damaged prestressed concrete girders.
