Study on Evaluation of Strength Properties of RC Beams Damaged by Corrosion of Tension Main Rebar

인장주근이 부식한 RC보의 내력성능 평가에 관한 연구

This study was carried out to investigate quantitatively the relationship between the degree of rebar corrosion and the strength of reinforced concrete 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 corrosion of tension main rebar. As a result, it was made that the strength of RC beams damged by corrosion could be practically simulated by FEM using experimentally determined material representing the bond properties and the mechanical properties of corroded rebars.
