Probability Distribution of Flexural Fatigue Life for Glass Fiber Reinforced Concrete

Abstract:

Through the fatigue experiments of glass fiber reinforced concrete (GFRC) specimens with 0%0.6%0.8% and 1% glass fiber volume fraction, the fatigue-lives of GFRC at various stress levels were obtained. The results indicate that the statistical distribution of fatigue-life of GFRC is in agreement with the two-parameter Weibull distribution. According to the statistical analysis of fatigue-life,the study shows the fatigue life of GFRC follows both the two-parameter Weibull distribution and three-parameter Weibull distribution, but three-parameter Weibull distribution is more suitable for expressing the law. Besides, the S-N curves and P-S-N curves which can be used to determine the life of GFRC under constant amplitude fatigue load were obtained.The results indicate that GFRC has distinguished anti-fatigue property.
