The timber concrete composite (TCC) construction method - originally developed to strengthen existing wood joist ceilings - is enjoying increasing interest, also in the construction of new residential and office buildings. The composite construction material utilizes the advantages of the materials involved and thus gets the "best of both worlds". In addition to the possible implementation of large spans and the favorable vibration behavior, the good sound and fire protection as well as the moisture protection contribute to the increasing attractiveness. If suitable systems are selected, high degrees of prefabrication can also be implemented.
The TCC construction method is not a new construction method. The first approaches are more than 80 years old and basically this construction method is well researched and developed. Nevertheless, it has not yet been possible to achieve a wide application. On the one hand, this is due to the lack of binding and generally accepted rules (such rules are on the way), on the other hand, the lack of a simple, easily comprehensible and transparent calculation and verification also stands in the way of a broader use due to the high calculation effort required. This is precisely where the project wants to start.
A clear project objective is the implementation of an effective and at the same time transparent design and thus an increase in competitiveness in the planning and design of TCC systems. A software tool is to be created with which the calculation and verification of the TCC components for the different systems can be carried out as far as possible automatically. The applicability of this software tool will be explored for prefabricated TCC slab elements in projects for subsequent roof constructions.
