Concrete cracking due to rebar corrosion is an important engineering pathology. Most of the numerical studies were based on the concrete models with normal volume ratios of aggregates and didn’t consider the surrounding constraints. We propose a new algorithm to generate aggregates of a high volume ratio and establish the meso-scale concrete model with consideration of the surrounding constraints. The model is verified against available experimental results. Then, a series of simulations are carried out to analyze the failure pattern of concrete caused by non-uniform rebar corrosion. The influences of surrounding structures, spatial and size distributions of aggregates, cover thickness, rebar diameter, and concrete tensile strength are discussed.
