In larger constructions, such as in construction of bridges and buildings, steel-concrete composite structures are employed to provide high strength and stiffness. These composite structures function based on the commonly- known fact that concrete is weak in tension but strong in compression. A natural consequence of this composite action is the shear flow between the concrete and the steel. In order to prevent slip from occurring between the concrete and steel sections, shear connectors are provided, thereby allowing the two components to behave as one1. The focus of this study is on shear connectors of the flexible type, which resist shear forces by bending, tension or shearing at the point of connection between the connector and the steel beam. The steel concrete composite construction has become an effective construction practice in the recent years. The cold form profiled sheet acts a platform for during the construction phase and acts as an external reinforcement after the construction. In steel concrete composite construction, the shear connectors transfer the longitudinal shear force across the steel flange/concrete interface. The ability to transfer the longitudinal shear force by shear connectors mainly depends on the strength of concrete against longitudinal cracking and mechanical properties of the shear connectors. Head stud and L-shaped shear connectors will be used and tested in this project.
