A Modified Concrete Virtual Internal Bond model (MC-VIB) for concrete is presented. The proposed model is a ‘fracture-constitutive’ model. The model’s seven material parameters are calibrated for compressive strength of 27.6 MPa. MC-VIB model is fairly insensitive to mesh size and shows structure size effect.
