Abstract: Abstract Cracking significantly affects the behaviors of reinforced concrete structures and periodically distributed fracture spacing phenomenon exist in the failure mode of the reinforced concrete structure, In this paper, a three dimension numerical test code named Realistic Failure Process Analysis was used to study the mechanisms of the fracture nucleation, formation, infill and saturation of the reinforced concrete structure. The numerical test results agree well with the experimental result not only on failure mode but also on the stress-strain distribution curve. Different stress field distribution is gained by five numerical tests results for the samples with different crack spacing, and in which it can be indicated the form mechanisms of fracture spacing phenomenon, and the numerical tests give the stress distribution rules by the ratio of fracture spacing to concrete protection thickness of the reinforced concrete samples.
