This paper presents the design method of shear-connectors in composite 2-I steel girder bridges. First, a three-span continuous composite bridge model is analyzed by 3-dimensional FEM and the characteristics of the behavior of shear-connectors is shown. Authors presents the simple method to obtain the stress resultants produced in the shear-connectors such as the longitudinal shear forces, the transverse shear forces and transverse bending moment. Finally, the present paper propose the design procedure for the shear-connectors.
