| Abstract | The main objective of the study was to evaluate the behavior and performance of concrete bridges strengthened with CFRP composites. The bridges with various superstructure configurations, including reinforced concrete slab and prestressed concrete girder, were studied. The behaviors of strengthened bridges were evaluated using diagnostic load tests. Three-dimensional finite element models were developed to investigate the distribution of wheel loads for various positions on the bridge spans. The results obtained from field testing and FEM models revealed that the overall load distribution was slightly altered from the CFRP strengthening system. However, the performance of bridge structures could considerably be enhanced by the strengthening system. |
