Abstrakt: As an advanced construction material, self-consolidating concrete (SCC) is a highly flowable concrete that is able to fill the formwork under its own weight without vibration. This paper presents a study on fatigue performance of SCC under flexural load. An experimental program has been carried out to investigate the fatigue lives of SCC for various levels of the fatigue stress. The fatigue tests on SCC beam specimens (100 × 100 × 400 mm) were conducted. The fatigue test data of SCC is used for regression analysis. The results indicate that the flexural fatigue life distribution of SCC approximately follow the doubleparameter Weibull distribution. The regression parameters of the fatigue equation corresponding to different survival probabilities have been obtained. The flexural fatigue strength of SCC for the desired level of survival probability can be estimated by using the fatigue equation. [ABSTRACT FROM AUTHOR]
