Specifically, the shear connector can resist the longitudinal shearing force on the overlapped surface of the concrete slab and the steel beam, so that the concrete slab and the steel beam cannot slide. At the same time, the shear connector can resist the 'lifting force' of the concrete slab and the steel beam with a separation trend. Therefore, what kind of shear connectors are used and arranged becomes the key for the combined structure to be able to exert the overall performance.
