Fatigue Behavior of Precorrosion Deformed Bars
Fatigue tests were conducted on natural corrosion deformed bars. The specimens were taken from a temporarily halted construction project. A method of mass loss was adopted in this study. High-cycle low-amplitude fatigue tests were performed to failure using five levels of cyclical stress range. The fatigue life of medium-corrosion deformed bars reduces sharply compared to that of noncorrosion ones. The failure mechanism in fatigue is examined by using a scanning electron microscope (SEM). Results indicate that the loss in fatigue life comes at the expense of the number of cycles needed to initiate fatigue cracks and is attributed to pitting corrosion.
