Abstract	On mesoscopic level, concrete can be treated as a three-phase composite material consisting of mortar, aggregates and interfacial transition zone (ITZ) between mortar and aggregate. A lot of research has confirmed that ITZ plays a crucial role in the mechanical fracture process of concrete. The aim of the present study is to propose a numerical method on meso-scale to analyze the failure mechanism of reinforced concrete (RC) structures under loading, and then it will help precisely predict the damage or the microcrack initiation and propagation of concrete. In this method, concrete is discretely meshed in terms of the Rigid Body Spring Model (RBSM), while the reinforcing steel bars are modeled as beam elements. The fracture process of concrete and the distribution of microcracks, as well as the load-deformation relationships are investigated and compared with the available experimental results. It is found that the numerical results are in good agreement with the experimental observations, indicating that the model can successfully simulate the fracture process of concrete and the distribution of cracks
