AbstractIn this work, to investigate the characteristics of non-uniform corrosion of steel bars more accurately, a new experimental method was proposed, which can rapidly generate non-uniformly distributed rust around steel bars in concrete. The precise average and critical cross-sectional area along the longitudinal direction of corroded steel bars were then obtained using the three-dimensional (3D) laser scanning. Based on critical section loss rate, the effects of non-uniform corrosion on the degradation of mechanical properties of steel bars were studied. The corrosion morphology, mechanical properties, and tensile failure patterns of uniformly and non-uniformly corroded steel bars were compared and elaborated.
