Abstract
This paper presents the understanding of scale effects in bending-active structures and a strategy for increasing the span to employ them for elastic kinetic roof systems. The aspect of scalability and the stability during the deformation in bending-active structures are not often regarded. Regardless of the self-similarity of bending, the problem can be identified as the increase of compressive stresses that could easily cause the instability in a scaled structure both during its active deformations and under external loading.The paper therefore proposes a concept of bending-active structures with built-in tension cable elements, which should improve the stability of the structure in a larger scale. A novel concept of elastic kinetic roofs shall be presented in accordance with comparative feasibility studies of bending-active plates for their structural behaviours in scales both at deformed and loaded configurations.
