Abstract

Steel fiber reinforced concrete (SFRC) will appear ununiform corrosion under chloride environment, resulting in corrosion-induced crack. However, the mechanism of corrosion-induced crack of ununiform corroded SFRC is not clear. In this paper, the 3D mesoscale numerical model of SFRC structure is established, the generation algorithm of round straight steel fiber is provided, and the corrosion-induced crack are simulated by XFEM, at the end the damage characteristic of ununiform corroded SFRC are studied. The result shows with the increase of rebar corrosion area, the number of corrosion-induced cracks increase gradually. The width of each corrosion-induced crack decreases linearly with the thickness of the protective layer, and the width of the penetrate crack decrease to 0.08 mm~1.2 mm.
