Abstract
- With the material testing machine of electro-hydraulic servo, fatigue test have been carried out on coarse aggregate concrete with pre-crack .The fatigue life and fatigue strength of the concrete have been measured under tension and compression loading. The effect of pre-crack on concrete fatigue behavior has been analyzed based on the test results. Having regression treatment, obtained the concrete S-N curve and S-lgN curve of fatigue life. Mean-while, applying ANSYS finite element software, analysis and comparison of the fatigue behavior have been performed. The results show that pre-crack has a great influence on the fatigue behavior of concrete, and the fatigue life is reduced for 75%~80%.
