Research has been conducted on the topic of protecting bridges from damage by being struck by tall vehicles, which may result in failure of the bridge system and loss of lives. Focus is on the assessment of the structural damage, suitable repair material, optimum repair method and repair configuration for impact-damaged girders. Carbon fiber reinforced polymer (CFRP) U-wrapping is showing promise as a repair option. Specifically, this article presents results of testing bridge girders to assess the use of CFRP to restore the capacity of laterally damaged concrete and prestressed concrete girders, investigate the effectiveness of using transverse U-wrappings to anchor and mitigate the longitudinal CFRP debonding problem, and investigate the fatigue behavior of CFRP-repaired prestressed concrete girders, among other aspects.
