Abstract This study presents a form-finding and fabrication methodology for large-scale bending-active structures using continuous fiber composites. Bending-active structures leverage the elastic deformation of flat and flexible materials to achieve freeform curved geometries. Traditional methods using metals, plastics, or fiber-reinforced polymers (FRPs) often encounter scalability challenges due to assembly requirements of multiple elements. To address this, the proposed strategy utilizes continuous fiber composites to construct bending-active surfaces from single flat sheets, enhancing both structural integrity and construction efficiency. Based on a literature review, the study analyzes the form-finding principles of active bending plates and the properties of continuous fiber composites to derive an optimal reinforcement strategy. Based on a literature review of form-finding principles and composite properties, two reinforcement strategies were developed: surfacial reinforcement to increase panel rigidity and topological reinforcement to improve global stability. These strategies were assessed through digital simulations and physical prototyping. A full-scale, vertically self-supporting pavilion was constructed to test real-world applicability, with performance compared to similar precedents. The results demonstrate that combining surfacial and topological reinforcement effectively reduces structural weaknesses, enabling the formation of stable, three-dimensional geometries. This approach streamlines material processing, shortens construction timelines, simplifies transportation and assembly, all while minimizing complexity. The proposed methodology expands the architectural application of continuous fiber composites, offering a structurally and economically efficient solution for large-span or geometrically complex structures, while contributing to sustainable construction practices through material optimization.
