Nonlinear numerical simulation of bond performance between recycled concrete and corroded steel bars

Abstract In this article, the bond performance between recycled concrete and corroded steel bars is analyzed by nonlinear numerical simulation. The result shows that maximum strength bar decreases with increase in corrosion rate; when large, simulated good agreement experimental strength; small, relatively poor strength, but there still an error within allowable range; slip increases rate exceeded 5%, more rapidly; specimen sizes under same diameter rate.
