Within this approach, the lightweight design offers material-efficient structures which, due to their reduced mass, provide a good basis for an energy-efficient actuation. In addition, the use of flexible component behavior provides the possibility to keep the number of required actuators as low as possible, while maintaining a high degree of adaptability. Therefore, the resulting active hybrid structures represent a promising approach with respect to the development of sustainable active structures in our built environment. Due to a larger number of relevant objectives, this new kind of structures requires a higher design effort compared to classical structures from the field of structural engineering. This dissertation aims to contribute to a more efficient and generalized design process for active hybrid structures. In order to achieve this goal, several strategies have been investigated. First of all, useful target criteria related to the mentioned relevant areas are derived. These should enable a more target-oriented design and provide a basis for formulating appropriate target weighting, allowing the development of ideal compromise solutions that combine structural stiffness, bending elastic transformation behavior and an efficient actuation concept. In addition, a variety of approaches have been investigated to improve the design process of active hybrid structures in a broad stress field between stiffness and compliance. These mainly include the aspects of structure generation, analyses for an optimal load transfer as well as the determination of an associated optimal actuation concept. In the context of this thesis, different subroutines are investigated for the mentioned partial steps of an overall hierarchical method which were implemented in a software application. Some variations of this generalized method were applied to diverse structural case studies of cantilevered systems with different degrees of structural stiffness. Three of these examples, representing segments of roof structures that differ in terms of their bending elastic transformation behavior, were analyzed in more detail in this thesis. These analysis results were verified on real active hybrid prototypes.}, subject = {Tragwerk; Leichtbau; Hybridbauweise; Bauentwurf; Software}, language = {en} }
