This paper deals with the analysis of corroded steel bar in concrete with emphasis on modeling the interaction between steel bar and concrete. The interaction of both materials is modeled by considering bond-slip relationships through the interface element. The model consists of a single steel bar and surrounding concrete using an axisymmetric model. Three types of bond-slip models are considered in finite element (FE) analysis; (1) bi-linear; (2) bi-linear with bond softening; and (3) tri-linear model. The input parameter of bond-slip model including maximum local bond stress, bond stiffness and bond softening is evaluated by degrading the bond and concrete tensile strength due to corrosion of steel bar. The models are assessed by comparing the FE analysis results with the experimental results of corroded tension members. From the analysis results, the tensile strength of concrete besides the maximum local bond stress and the bond stiffness give a significant effect on tension stiffening and cracking behavior.
