steel girders/Steel Box Girder/Steel-Concrete Composite Deck provide the means to achieve composite action between the slab and the girders, thus increasing both stiffness and strength.
Shear connectors between concrete slabs and steel beams in composite construction can play an important role in the seismic response of a structure. They provide the necessary shear connection for composite action in flexure and can be used to distribute the large horizontal inertial forces in the slab to the main lateral load resisting elements of the structure.
