A handily model to evaluate the bending resistance and the ductility of corroded beams critical in flexure and shear is proposed and debated. Effects of diffused and pitting corrosion on steel bars, compressive concrete strength reduction and concrete bond strength reduction due to rust creation are modelled. Practical method derived on limit state theory was here used to calculate the flexural and shear strength and the available ductility. The effectiveness of the model was also corroborated against numerous results collected in the literature pertaining to bending and shear resistance.
