• Abstract:
  The enhancement of load rating concrete structures by the installation of Fiber reinforced ; polymer strips (FRP) is becoming a preferred short-term action. The addition of supplemental ; tensile capacity to concrete beams by applying high tensile strength FRP strips to the exterior ; of concrete structures provides immediate increase in live load capacity. ; This study assessed the installation, theory and effectiveness of adding external FRP ; reinforcement. The assessment of the connections of the FRP strip to the concrete structure ; warrant further study to determine development strengths and bearing capacity. ; Analysis of the system confirmed that it is a cost effective technique to increase load rating for ; concrete pier cap applications. Supplemental detailing to include improved shear connection ; at the bolting points may provide an improved in-place performance of the FRP.
