Summary
The advantages of the two different building construction materials, timber and concrete, can be used effectively in adhesive-bonded timber-concrete composite constructions. The long-term behavior was investigated experimentally on small-scale shear and bond specimens under artificial, alternating climatic conditions and on fullscale specimens under natural climatic conditions for an application in construction practice. The development of the shear strength and the deformation behavior under permanent loads were studied, focusing on the different material behavior of wood and concrete regarding changes in temperature and moisture. The general applicability of adhesivebonded timber-concrete composites in construction practice was proved in the investigations.

Summary
The long-term behavior of adhesive-bonded timber-concrete composites is influenced by climaticchanges in temperature and relative humidity because of the different properties of wood, concrete and adhesive. Threedimensional material models, which take into account the hygrothermal and time-dependent behavior, were developed to predict the long-term behavior. The material behavior of the wood is highly influenced by the moisture content. Thus, the wood moisture content was calculated numerically as well as depending on the surrounding climatic conditions. The numerical models were validated with data from experimental investigations and applied to determine climatic conditions for further experimental investigations.
