抄録	This paper presents an experimental study on the flexural fatigue characteristics of PVA-ECC and PE-ECC. The ECCs showed a unique S-N relationship and exhibited the development of multiple cracks even under fatigue loading. The development of multiple cracks was found to be dependent on fatigue stress levels, and the mechanism is discussed in reference to the static multiple cracking mechanism. The difference between the two ECCs appeared especially in the deformation capacity under fatigue loading. The deformation is shown to be affected by the number of cracks as well as the crack width, where the fracture mechanism of a bridged crack is related to either fiber rupture or fiber pullout.
