The proposed thesis contributes to the ongoing research on bending-active structures conducted by the institutes ITKE and ICD at the University of Stuttgart. This research aims to employ tension force towards developing a novel approach for the assembly process in large-scale bending-active plate structures. Throughout the investigations of this research, this aim was achieved within a formation process that generated the possibility of planar strips with different paths and configurations to be bent into shape and place employing contraction of a few continuous tensioned cables. The developed digital tool contributes to the existing methods by including the creation of developable strips out of discretized segments that represent the desired target surface in different path scenarios.

To optimize and refine the notion of tension-based assembly, this research contributed theoretically and geometrically by detecting and developing the affecting parameters. These theories were generated intuitively and developed digitally within the developed digital tool. Then, the accuracy and effect of the parameters were tested though a defined setup of physical tests and evaluated though the continuous collaboration of physical and digital processes within the feedback loop. Finally, the research results in the development of a user-friendly interface from design-to-assembly of large-scale strip-based bending-active structures.
