Modeling the Behavior of Insulated FRP-Strengthened Reinforced Concrete Beams Exposed to Fire

Article Preview

External bonding of fiber reinforced polymer (FRP) composites has become a popular technique for strengthening reinforced concrete (RC) structures all over the world. So far, very little information is available on the fire performance of FRP-strengthened concrete members. The analysis presented here aims to develop a nonlinear finite element (FE) model of FRP-strengthened RC beams exposed to fire. The analysis consists of two portions: the initial portion is the calculation of the transient temperature distribution and the second portion is the structural response analysis due to the effect of thermal and mechanical load. The proposed numerical analysis is validated against proving fire tests. The results indicate that the predicted temperatures and deformations are shown to agree to the tests satisfactorily.
