摘要：

In this article, the flexural fatigue tests of self-compacting rubberized concrete (SCRC) with different waste tire rubber contents were done to study the fatigue mechanical behavior. The result shows that the monotonic curve can well describe the fatigue failure strain. What's more, both the secondary strain rate per cycle and secondary stiffness rate per cycle can describe the flexural fatigue life of SCRC, and relationships are independent of the rubber content. Finally, the fatigue damage evolution model was proposed based on Weibull function, and it can be used to predict the fatigue damage evolution of SCRC accurately.
