摘要：
To enable a reliable analysis of the residual behavior of corroded rebars，a computationally-efficient method capable of considering the corrosion morphology characteristics was proposed by the probability distribution function of the cross-section area. The degraded mechanical properties of rebars under different corrosion rates were quantitatively studied based on the combination of Monte Carlo method and numerical tensile tests of corroded rebars. This method can accurately estimate the mechanical properties of corroded rebars verified with previous test results，especially for the deformation capacity. The effects of constitutive laws and gauge lengths were analyzed respectively. The results show that the strength yield ratio of rebars is the dominant issue governing deformation capacity after being corroded，and different gauge lengths are responsible for the different calculation results of the ultimate strain of corroded rebars. © 2024 Editorial Board of Jilin University.
