In the traditional way floors has been constructed there are no shear connectors between the concrete slab and timber joists. In this study, an existing floor system os improved by simply providing normal bolts or lag screw so that the composite action can be achieved. It is evident that the key elements in the composite beam are the shear connectors. The selection of these connectors was based on their shear capacity. The experimental study carried out in this research investigated the flexural behavior of composite beams. The experimental studies of composite beams showed that the ultimated load capacity of the proposed composite beam(LS-S10 specimen) is 1.29 times as high as the noncomposite one. Finally, it can be concluded that LS-S10 specimen consisting structural laminated timber beam and concrete slab can be significantly improved by providing appropriate shear connectors.
