TY - JOUR ID - TI - Numerical Study on the Performance of GFRP RC Beams Exposed to High Temperature AU - Nuha Hussien AU - Haitham Al-Thairy PY - 2020 VL - 13 IS - 2 SP - 136 EP - 143 JO - Al-Qadisiyah Journal for Engineering Sciences مجلة القادسية للعلوم الهندسية SN - 19984456 24117773 AB - This paper presents and validates a numerical model utilizing the nonlinear finite element software ABAQUS/Standard to simulate the performance and failure of Glass Fibre Reinforced Polymers reinforced concrete beams under high temperature. A numerical model was firstly developed by selecting the proper geometrical and material modeling parameters with suitable analysis procedures available in ABAQUS/Standard. The developed numerical model was verified by comparing numerical results with the corresponding results of the experimental test extracted from the current study on Glass Fibre reinforced concrete beams under different elevated temperatures ranges from (20 to 600ºC). Validation results have indicated the accuracy of the suggested numerical model. The validated numerical model was implemented to investigate the effect of important parameters on the performance and maximum load of Glass Fibre reinforced concrete beams under different elevated temperatures that are not considered in the current experimental tests. These parameters include the effect of exposure time or time-temperature history and effect of temperature distribution around the beams
