The objective of this investigation was to find out the feasibility of using composite beams consisting structural laminated timber beam and concrete slab in residental and commercial building. 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 under repeated loading. Also, the push out tests performed to evaluate shear performance of shear connectors, that is, bolt, lag screw, and nails. The penetration depths(4d, 6d, and 9d), where d is the diameter of shear connectors. There is no significant difference between the strength of the shear connectors driven into the timber joists 6times their diameter and 9 times their diameter. Hence, it is concluded that the required depth to obtain a sufficient strength for the shear connectors is 6 times its diameter. And, 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.
