The combination of a timber structure with concrete components. The optimization of manufacturing methods in order to optimize a composite system by using the best product of each material. Engineering knowledge shall be amended and stimulated by the development of design rules and approaches.
The objective of this thesis is to provide a framework to evaluate economical and technical factors. For concrete-timber innovations in the construction market.
Timber-concrete composite systems are being increasingly used for upgrading of existing timber floors. In residential or buildings as well as for new buildings and bridges. These kinds of structures consist of timber joists or beams actively interconnected to a concrete slab.
This insight has been first confirmed by freely talking to various experts in both timber and concrete markets, including the international concrete company.
In timber-concrete composite structures, the concrete slab mainly resists compression, while the timber joist resists tension and bending and the connection system transmits the shear forces between the two components.
Advantages:
1.The increased load-carrying capacity of the building
2.Higher stillness (which leads to a reduction in the sections and susceptibility to vibrations)
3.Improved acoustics and thermal properties
4.Higher fire resistance in timber

There are also some advantages relative to normal reinforced concrete floors. Notably, cracks in the tensile region of reinforced concrete slabs may promote penetration of moisture and corrosion of the steel rebars.
Thus, the design of timber concrete composite structures generally requires consideration of the slip occurring so the joint between the timber and concrete.
