Item Open Access Integrative numerical techniques for fibre reinforced polymers - forming process and analysis of differentiated anisotropy(2013) Waimer, Frédéric; La Magna, Riccardo; Knippers, JanIn the current paper, the authors developed two different numerical methods for fibre reinforced polymers. The first method deals with the simulation of an innovative manufacturing process based on filament winding for glass and carbon fibre reinforced polymers. The second developed numerical method aims at modelling a high level of material complexity and allowing reciprocal confrontation with a geometric differentiated global structure. The developed numerical techniques served as a basis for the design and implementation of a Pavilion built on the campus of the University of Stuttgart in 2012 and could thus be tested and proved.Item Open Access Integrated design methods for the simulation of fibre-based structures(2013) Waimer, Frédéric; La Magna, Riccardo; Reichert, Steffen; Schwinn, Tobias; Menges, Achim; Knippers, JanThe production of structural components based on fibre-reinforced polymers (FRP) for the building industry is still characterised by a classic downstream development process from design through engineering and down to fabrication. In the aerospace and automotive industry, the current technical developments in simulation and manufacturing processes have reached a highly advanced status. Nevertheless, these manufacturing and Analysis processes are in most cases non-transferable or unsuitable for architectural and structural purposes. The goal of the research presented in this paper is to take advantage of the benefits of FRPs within the architectural domain - focusing on material efficiency, durability and light-weight construction - and to find solutions for the problem of transferability into the building scale. For the construction of a Pavilion built on the campus of the University of Stuttgart in 2012, process-specific tools with a high degree of accuracy embedded from the start were developed for the material analysis, optimisation and fabrication steps. In contrast to product prototyping, which forms the basis of industrial mass production, prototype here refers to the establishment of processes within the context of a post-industrial, customised fabrication paradigm.Item Open Access Segmented timber shells for circular construction : relocation, structural assessment, and robotic fabrication of a modular, lightweight timber structure(2025) Bechert, Simon; Aicher, Simon; Gorokhova, Lyudmila; Balangé, Laura; Göbel, Monika; Schwieger, Volker; Menges, Achim; Knippers, JanSegmented timber shells present a novel building system that utilizes modular, planar building components to create lightweight free-form structures in architecture. Recent advancements in the research field of segmented timber shells pursue, among others, two fundamentally opposing research objectives. 1. The modularity of their building components facilitates the reuse of such structures in response to a changing built environment. 2. Advanced developments aim at establishing segmented timber shells as permanent building structures for sustainable architecture. This paper addresses the first research objective through the successful relocation of the BUGA Wood Pavilion in the context of the proposed methodology of Co-Design for circular construction. The methods and results involve integrative design and engineering processes and advanced quality assessment methods, including structural, geodetic, and physical properties for modular timber constructions. The BUGA Wood Pavilion serves as a building demonstrator for the presented research on segmented shells as lightweight, reusable, and durable timber structures.
