Predicting the Remaining Service Life of Reinforced Concrete Members after Fire Exposure
An experimental program was conducted to investigate the effect of elevated temperatures on bond between reinforcing steel and concrete. By regressing the pullout test data, simple empirical models were proposed to predict the percentage reduction in bond strength accounted for effects of high temperature. Based on the empirical models, the resistance and the reliability of RC members after fire were analyzed using J.C. method. The engineering example indicates that the method of reliability analysis is suitable for predicting the change of post-fire resistance with temperature.
