Abstract Sixty three glass fiber reinforced concrete (GFRC) beam specimens of size 100×100×400mm were tested under four-point flexural fatigue loading by electro-hydraulic universal testing system (MTS) to obtain the fatigue-lives of GFRC at various stress levels. The specimens incorporated 0.6%, 0.8% and 1% glass fiber volume fraction. The results indicate that the statistical distribution of fatigue-life of GFRC is in agreement with the two-parameter Weibull distribution. The coefficients of the fatigue equation have been determined corresponding to different survival probabilities so as to predict the flexural fatigue strength of GFRC for the desired level of survival probability.
