This article studies the fatigue fracture characteristics of the corroded steel strand in PC beams by means of experiments. In addition, based on observing the fracture morphology of the corroded strand, this article analyzes the mechanism for the fatigue fracture as well as the fracture morphology formation, which is of certain practical significance in this field.
