Abstract: This paper presents a study on fatigue behavior of non-fibrous concrete and SFRC subjected to repeated loading. It is aimed to study the behavior of Non fibrous concrete and SFRC under constant amplitude and compound amplitude loading. A total number of 140 prism specimens of size 75x100x500 mm were tested under flexural fatigue loading using havier sine wave loading in order to obtain the fatigue lives of Non fibrous concrete and SFRC at different stress levels. About 10 prism specimens are subjected to static flexural test to determine the static flexural strength of Non fibrous concrete and SFRC prior to fatigue testing. The specimens incorporated 1% volume fraction of crimped steel fibers of size 0.55mmɸ X30 mm. About 30 prism specimens were tested under constant amplitude fatigue loading. Fatigue life data obtained has been analyzed in attempt to determine the relationship among stress level and number of cycles of failure. About 110 prism specimen was tested under compound fatigue loading in order to check the validity of miner’s hypothesis.
