Summary:•This numerical model is developed based on 3D discrete meso-scale approach.•New pull-out test is designed for developing the constitutive models of corroded interface.•Effects of non-uniform corrosion on the behavior of corroded RC beams are investigated.•Failure of corroded RC beam is successfully simulated by 3D RBSM.•Failure process and beam’s stiffness changing are revealed through the study of simulation results.
