Abstract: Steel-Concrete composite beams have been used for a considerable time in bridge and building construction. Shear connector is important for steel concrete composite structures. It is used as a shear resistance in the steel concrete interface. This study presents an investigation on static behavior of multi-stud shear connectors in composite beams, suitable for transferring shear force in composite structures by analytical way. The composite section have been modeled in ANSYS with the help of finite element modeling and analyzed, the results have been documented for comparison. Once the composite sections have been casted, it is made to undergo Standard Push out tests. The test is been carried out to analyze various parameters like load-slip behavior, shear resistance, bearing capacity, ductility and also the failure modes of multi-stud shear connectors used will be detailed. The effective and economical ways of using the stud shear connectors in Steel-Concrete composite sections will be discussed. Finally the result shows that the ultimate strength of multi-stud is about 18% larger than single stud. The slip of single stud specimen is about 25% larger than multi-stud specimens. These results may be useful in the design of steel-concrete composite bridges. Furthermore the comparisons of the results of various arrangements of multi-stud shear connectors used will be documented.
