Abstract
In a composite beam, a shear connector is installed to resist the horizontal shear on an interface between steel beams and reinforced concrete slabs. The steel-wire-integrated deck plate slab is commonly used at the wide section beam. Then vertical bars are installed at the upper wire of the ends of the steel truss girder to ensure safety during the construction. The new type of shear connector is made of deformed bar and steel plates, and must function as vertical bars but must have higher shear capacity. This paper examines the ways to develop and utilize this new shear connector. From the push-out experiments, a shear connector made of a continuous deformed bar and steel plate showed a higher shear capacity and ductility than a ${\phi}16$ stud connector, and functioned as a vertical bar.
