The growing consumption of resources in the building industry has a worldwide negative impact, as it leads to inflation and an increased environmental impact. Construction resources are valuable and not available in unlimited quantities, therefore, how they are handled is of great importance. First attempts of implementing this state of mind within the construction industry have reached the masses with ongoing research to optimise various construction methods. Part of this research concerns the appropriate combination of wood and concrete materials. This combination, also known timber-concrete-composite, short TCC, is already widely used in practice today for ceiling constructions. The conventional connection methods, such as notches and screws, still offer considerable potential for improvement of the system stiffness as well as regarding use of primary resources and circularity. A possible improvement can be achieved by using adhesive bonds, which not only allow for a continuously shear transmission between the components but are also easier to produce and separate once the construction element is no longer needed. The aim of this doctoral thesis is to investigate, assess and optimise all aspects of TCC ceilings, such as the load-bearing behaviour, manufacturing, maintenance, dismantling and recyclability.
