Fiber-reinforced polymer (FRP) reinforced concrete are made by combining a plastic polymer resin together with strong fibers reinforced with concrete. This materials are commonly used in building structure. One of main safety requirements in structural is the fire protection requirements. It is important to understand the behavior of FRP reinforced concrete when the temperature increase (20-250°C) and high (>250°C) are challenging and important. Severe degradation and bond properties will be effected when the temperature increase. Therefore, in order to understand the structural behavior, the thermal response of FRP reinforced concrete under elevated and high temperature needs be understood and predicted. In this study, Finite Difference Method (FDM) will be used to solve the heat transfer model to study the behavior of FRP composite in thermal aspects. The numerical algorithm of FDM heat transfer model will be constructed and used to analyze the heat thermal response of FRP composite. The temperature result obtained by the numerical method will be validated with data test.
