Development of a prefabricated timber-concrete composite slab

Although a lot of research in the field of timber-concrete composite systems has been carried out during the last years this systems are not very often used in practice. Due to the fact that in most cases nowadays the concrete of the timber-concrete composite structures is cast in place a lot of humidity is brought into the building and the construction period compared with pure timber constructions is much longer. Thus the development of a timber-concrete-composite system consisting of completely prefabricated timber and concrete elements was obvious. The two parts - timber element and precast concrete layer - are fabricated in different specialised facilities, delivered on site separately and finally connected with a shear connecting device. This paper introduces the new system and reports about short term tests of the new developed shear connectors.
