This study aims to use a small-scale model to investigate the corrosion effect on the degradation of reinforced concrete RC footings and to compare its observations with prototype-scale research results using a numerical model for footings exposed to various corrosion levels under eccentric loading. This comparison may be used to assess the efficacy of small-scale models in expressing prototype models in order to save money and time. The finite element method was used in collaboration with the ABAQUS software to study its impact on eccentric load behavior with several corrosion levels. This research also examines the influence of concrete depth on its behavior under different corrosion levels and eccentric loads with varying eccentricities. As both the corrosion ratio and the depth of the RC footing increased, the cracking pattern in the concrete became more pronounced, the extent of corrosion in the bars grew, and the difference in failure load also increased. Using the FEM, the findings will be beneficial in estimating the performance of isolated footings with corrosion damage.
