This paper reviews the type of engineered timbers and connection systems used in timber concrete composite structures. The literature references were selected and reviewed carefully to get a detailed overview of the use of timber and connections systems in timber-concrete composite structures. The list of connection systems used in the timber-concrete composite structures was reviewed from the previous works to perceive its advantages and disadvantages. It was found that the glued joint is the stiffest connection but low in ductility. Mechanical fasteners such as screw connections have moderate stiffness and ductility compared to the hardwood studs which have the lowest stiffness and the highest ductility. The design models of connection strength and stiffness of the screw connections were assembled and discussed to recognise their limitations to the design of timber-concrete composite structures. © 2023, Strojarski Facultet.
