摘要

Timber-concrete-composite structures are strongly influenced by the time-dependent behavior of the components timber and concrete. Therefore creep and shrinkage have to be considered. Due to the interaction of both components, stress redistributions take place. This leads to effective creep values, which differ from the material creep coefficients. In order to take these effects into account in the structural design, the determination of effective creep values and the consideration of shrinkage in the design method according Eurocode 5 1994 are shown in the following.
