The timber concrete composite (TCC) construction method - originally developed to strengthen existing wood joist ceilings - is becoming increasingly popular in the construction of new residential and office buildings. The composite construction material uses the advantages of the materials involved and thus gets the "best of both worlds". In addition to the possible implementation of large ceiling spans and the favorable reaction to vibration, the good sound and fire proof qualities as well as the moisture resistance contribute to its increasing attractiveness. If suitable systems are selected, high degrees of prefabrication are possible.
The TCC construction method is not new. The first approaches are more than 80 years old and it has been well researched and developed. Nevertheless, it has not yet been possible to achieve a wide application. This is due to the lack of binding and generally accepted regulations (such regulations are in process), as well as the lack of a simple, easy to understand and transparent calculation and verification method. This is precisely the target of this project.
A clear project objective is to create an effective and at the same time transparent design for TCC systems and thus increase its competitiveness. A software tool is to be created with which the calculation and verification of TCC components for the different systems can be carried out automatically as far as possible. The applicability of this software tool will be explored for prefabricated TCC slab elements in projects for subsequent roof constructions.
