  Continuous composite girders are frequently used for railway bridges. Their features are characterized by perfobond strips and steel fiber reinforcement concrete. In this study, the behavior of cracks is investigated in comparison with experimental results of test specimens with perfobond strips and those with studs. In addition, experimental results of test specimens with steel fiber reinforcement are examined from the viewpoint of the effect of reinforcement on cracks. The validity of the tension stiffening theory was confirmed by a comparison between experimental and numerical results.
