    When we design the bridge of the composite girder, we assume that it is the complete composition that has infinite shear stiffness. But, because the girder and slab are composed with different materials, the problem can come out when we join the different members in the bridge. Moreover, the deflection, crack, and the damage of the concrete caused because of service load and repeated load promote the incomplete composition behavior. In the span in the bridge, the degree of the incomplete composition can change, thus, we needed to research about the relationships between the deflection, slip and the degree of the incomplete composition. Thus, in this research, we controlled the concentrated load and uniform load in the two continuous beam spans. So, we reserved the point near the area of negative moment when there is a deflection of crack and there is not a deflection of crack. And, we observed slip and deflection when there is crack and there is not crack by changing the interval of the studs. We used the Eurocode 4 because we wanted to consider the crack of concrete in the point of the continuous internal support beam. To observe the incomplete composition behavior, we used the three dimensional analysis programs by using finite element analysis program in a randomly picked point. We analyzed and compared the data by using the method of deflection ratio estimation method proposed by Jasim and the method of finite element analysis.
