This study was carried out to investigate quantitatively the relationship between the degree of rebar corrosion and the strength of reinforced concrete (RC) beams. After producing equations for the relationship between both the tensile properties of rebars and bond properties and the corrosion percentage of rebars, finite element analysis and bending tests were conducted for RC beams damaged by rebar corrosion. As a result, it was made clear that the strength of RC beams damaged by corrosion could be practically simulated by FEM using experimentally determined material models representing the bond properties and the mechanical properties of corroded rebars.
