In order to establish a grading method of corroded high-tensile steel wires,samples of steel wire served for more than a decade on four arch bridges were employed and the mechanical properties were investigated from the tensile and fatigue tests.The effect of pitting geometries was analyzed by finite element method(FEM)and tension test,and pits were simulated by means of notches on the surface of steel wires.According to the theoretical analysis and experimental results,the quantitative relationship between the pitting geometries and the ultimate strain of wire was proposed,and a grading method based on pitting geometries was developed.The results show that the elastic modulus and the ultimate strength of the wire are not sensitive to,while the ductility is significantly influenced by the pitting corrosion.Besides,stress concentration around the pitting is the cause of the decline in ductility of corroded high-tensile steel wires.The status of corroded wires can be evaluated precisely by the depth and shape of pits.
