Timber Engineering

Materials, connections and digital manufacturing technologies

The mission of the group is to contribute to the research and development of innovative material systems and solutions for modern timber engineering. A key motivation is to increase the competitiveness of wood in the construction sector, i.e. to promote a more sustainably built environment. Measures such as optimization of resource efficiency or increase of longevity of timber structures are supported through modelling, simulation, and experimental testing. The group is affiliated to the Institute of Construction Materials (IWB) and to the Department of Timber Constructions at the Materials Testing Institute University of Stuttgart (MPA). We take part in the teaching curriculum of University of Stuttgart.
