Abstract

In this paper, the fretting fatigue behavior of pretensioned high-strength steel monostrands is investigated. A method based on the digital image correlation (DIC) technique was used to quantify the relative movement between individual wires along the length of the monostrand. The experimental data indicate that the interwire movement due to transverse deformations is highest at the neutral axis of the monostrand. The results showthat the midspan and the anchorage of the monostrand are the two locationswhere the combination of tensile strains and the interwire friction is the most unfavorable. Moreover, the paper provides relevant information about the monostrand bending stiffness and the extent of relative displacement between core and outer wires of the monostrand undergoing flexural deformations. The results presented herein are of special interest for the fatigue analysis of modern stay cable assemblies where fretting constitutes the main mechanism of the fatigue life reduction. © 2013 Taylor & Francis Group, London, UK.
