The present master thesis was created within the scope of the research project "WooCon" "Wood-based concrete: building construction with composite elements of wood-concrete compound timber" sponsored by the FWF (science fund). In the course of this project, the department of structural engineering and timber engineering (ITI) developed composite construction by using a compound system out of ecological timber and wood-based concrete. The main objective of the following thesis is to compare the economic efficiency of composite elements of wood-concrete compound timber, developed at ITI with conventional ceiling systems. Under specified conditions the different ceiling systems are opposed on economic efficiency, as well as their aspects of ecological and physical construction. Moreover, the ceiling systems are examined depending on different spans and their respective costs are compared. To achieve this goal, the basics of composite elements of wood-concrete compound timber are discussed at the beginning. Then the boundary conditions for the comparison are chosen in order to limit the scope of this thesis. The ceiling systems are calculated depending on the different spans and the resulting component thicknesses are examined on the basis of their physical construction and ecological aspects. Depending on their spans the ceiling constructions are then scrutinized for economic efficiency. For this purpose, the individual costs of the ceiling systems are determined and listed tabular. Finally, the outcome of the physical construction and ecological examination is considered and valued with the individual costs. The analysis has shown that composite elements of wood-concrete compound timber is a successful alternative to the conventional ceiling systems. However, the main condition for this would be a substantial cheaper version of the intermediate layer made out of wood-concrete, compared to available products on the market. Based on this assumption the construction method can compete against the conventional timber-concrete composite slab in all investigated ranges. Nevertheless, the analysis has shown that none of the timber or composite slabs can compete with a reinforced-concrete ceiling in terms of their economic efficiency.
