This paper represents an effect of artificial crack length for fatigue load carrying mechanism of cracked reinforced concrete (RC) beams without stirrups. To make clear the mechanism, loading experiments and finite element analyses were conducted by using the beams which have artificial cracks instead of corrosion cracks. As a result, the gradient of decrease in the fatigue strength of the beams whose static strength was enhanced due to tied arch action became remarkably high. The cause could be explained by localization of damage accumulating area which was characterized by a shape of the load path. It was confirmed that the load path was attracted at the position of crack tips when the crack tips existed in B-region. The results represented a possibility that decrease in the fatigue strength of RC beams could be controlled by change in the shape of the load path.
