Abstract
This paper discusses application of Fiber Reinforced Polymer (FRP) composite plates to strengthen a capbeam of a bridge in New York State. Addition of a concrete wearing surface and a median barrier, led to an increase in dead load moment and shear, and resulted in flexural and shear cracking of the concrete capbeam. The capbeam was accordingly strengthened to improve its moment and shear capacities using bonded FRP composite plates. The capbeam was load-tested before and after the plates were installed, to investigate effectiveness of the strengthening system. Some of the results from these tests are presented and compared with those obtained using finite element analysis.
