Deflection of a prestressed concrete beam reinforced with carbon fibers at elevated temperatures
Fiber reinforced polymer (FRP) have unique advantages like high strength to weight ratio, excellent corrosion resistance, improving deformability and cost effectiveness. These advantages have gained wide acceptance in civil engineering applications. FRP tendons for prestressing applications are emerging as one of the most promising technologies in the civil engineering industry. However, the behavior of such members under the influence of elevated temperatures is still unknown. This study examines the deflection behavior of the carbon fiber reinforced polymer (CFRP) prestressed concrete beam at elevated temperatures. In this article, an analytical model is developed which integrates the temperature dependent changes of E-modulus of FRP in predicting the deflection behavior of CFRP prestressed concrete beams within the range of practical temperatures. This model is compared with a finite element model of a simply supported concrete beam prestressed with CFRP subjected to practical elevated temperatures. It was found that the results of model correlated well with the finite element model. Finally, a practical application is provided.
