For the studs in the composite beam under bending effect, axiel stress should be taken into account as well as the shear stress. This condition emphasizes the adherence between the studs and the concrete slab. Under the cyclic loading effect, lateral displacement of the stud leads to cavities in the concrete slab. These cavities affect the service life of the composite system. In this study, composite beams with fixed span and section properties are analyzed for different stud layouts. Reference specimens are strengthened with the use of tendon. This strengthening with the tendon has been made in order to limit the stress and deflection demands of the studs. For this purpose, experimental and numerical analyzes are carried out. Ansys Work Bench finite element program has been used for the numerical analysis. From the analysis results, stud count and the layout has been observed to be effective on the system behavior. For the lateral displacement of the system, the double row and the staggered layouts has given better results compared to the single row layout. It has been observed that the tendon added to the system has affected the stud stress distributions and stud lateral displacements positively. In addition, the tendon has contributed to the system capacity and the ductility.
