The last decades have seen great development of modern technologies with the use of wood in construction. Attention should be given to the flooring systems solution that use T-shaped beams made of wood and concrete. This work describes an experimental investigation in which round steel bars were used to connect timber to concrete. Symmetric, three-member specimens were built; the outside pieces were wood, the inside was made of concrete. The connectors consisted of straight pins with heads, cut from the bars, inserted normally to the wood surface and shaped like arches. These specimens were tested in compression and force-displacement diagrams and strenght data were obtained. The diagrams gave information on the fracture process and the stiffness that may be related to the ultimate and service limit states. The obtained results showed strength was high in all cases, with ductile process. It was also found arch-shaped connectors gave stiffer joints.
