Composite concrete beams construction separate widely in buildings and bridges for economical purposes. Some international specifications and codes present design rules to predict nominal shear and flexural strength for a composite concrete beam, one of them is ACI 318M-14. The contributions of the concrete slab and composite action to the vertical shear and moment strength of composite concrete beams are not considered in current design specifications and codes. In this paper, a comparative study deals with shear and bending moment capacity and shear stress of composite concrete beams is presented. The work includes a comparison between experimental tests results, ACI 318M-14 nominal shear and flexural strengths and finite element results. The ACI 318M-14 failed to predict the ultimate capacities, while the finite element analysis results compare satisfactorily with the experimental ones.
