Abstract

•The stress-control tensile fatigue behavior of UHTCC is investigated.•Four stages were observed in the evolution curve of fatigue deformation.•Smooth and rough areas can be distinguished on the fatigue failure surfaces.•Novel P-S-N models based on a modified S-N relation are proposed.•Using high-strength high-modulus fibers to replace partial PVA fibers in UHTCCs may improve the fatigue performance.
