Elastic kinetic structures are a recent approach to design transformable structures. Their transformation is based on elastic bending, that is compliant component behavior of structural members. This principle can be used to realize transformable structures with a stable deployment process. Regardless of a stable transformation, elastic kinetic structures are prone to static and dynamic loads due to their lightweight design. However, most of current research on these structures solely focuses on the principles of transformation. This paper proposes a concept for an active hybrid roof structure with a transformation based on elastic kinetics and rigid-body motion. The concept exhibits a stable structural deployment and active control components to counteract static and dynamic disturbances. Furthermore, this paper includes the realization and experimental evaluation of a mid-scale prototype structure.

Die angestrebten Ziele einer Ressourcen‐ und Klimaneutralität erfordern ein radikaleres Umdenken der Bauschaffenden, das mit einer noch viel stärkeren Sensibilisierung der Auftraggeber für die Auswirkungen des Material‐ und Energieverbrauchs im Bausektor verbunden ist. Ein Ansatz, um diese Ziele zu erreichen, sind hybride Konstruktionen, in denen unterschiedliche Materialien, Elemente, Funktionen und Technologien auf mehreren Konstruktionsebenen ressourcen‐ und energieeffizient kombiniert sowie im Fall eines Rückbaus sortenrein rezykliert werden. Dieser anspruchsvolle Ansatz ist von Beginn an erklärtes Ziel des Lehrstuhls Hybride Konstruktionen – Massivbau an der BTU Cottbus‐Senftenberg und zieht sich durch alle Lehr‐ und Forschungsaktivitäten. Mit ausgewählten Forschungsprojekten werden Motivation und Methoden hybrider Konstruktionen sowie deren Potenzial für ressourcen‐ und klimaneutrale Konstruktionen anhand von Prototypen aufgezeigt. Hierbei steht neben der ökologischen Weiterentwicklung klassischer hybrider Konstruktionen aus nachwachsenden und rezyklierten Rohstoffen, bspw. Holz und Recyclingbeton, auch die Entwicklung aktiver hybrider Konstruktionen im Fokus. Die gezielte Integration von aktiven Technologien wie Sensorik, Aktuatorik und Regelungstechnik ermöglicht multifunktionale Konstruktionen, einen hohen Nutzungskomfort, einen geringeren Rohstoffverbrauch bis hin zur Energiegewinnung aus dynamischen Einwirkungen.
