    Co-design methods for non-standard multi-storey timber buildings
    (2023) Orozco, Luis; Krtschil, Anna; Wagner, Hans Jakob; Bechert, Simon; Amtsberg, Felix; Knippers, Jan; Menges, Achim
    To meet climate change goals and respond to increased global urbanisation, the building industry needs to improve both its building technology and its design methods. Constrained urban environments and building stock extensions are challenges for standard timber construction. Co-design promises to better integrate disciplines and processes, promising smaller feedback loops for design iteration and building verification. This article describes the integrated design, fabrication, and construction processes of a timber building prototype as a case study for the application of co-design methods. Emphasis is placed on the development of design and engineering methods, fabrication and construction processes, and materials and building systems. The development of the building prototype builds on previous research in robotic fabrication (including prefabrication, task distribution, and augmented reality integration), agent-based modelling (ABM) for the design and optimisation of structural components, and the systematisation of timber buildings and their components. The results presented in this article include a functional example of co-design from which best practises may be extrapolated as part of an inductive approach to design research. The prototype, with its co-designed process and resultant flat ceilings, integrated services, wide spans, and design adaptability for irregular column locations, has the potential to expand the design potential of multi-storey timber buildings.

    Integrated design methods for the simulation of fibre-based structures
    (2013) Waimer, Frédéric; La Magna, Riccardo; Reichert, Steffen; Schwinn, Tobias; Menges, Achim; Knippers, Jan
    The 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.

    Extension of computational co-design methods for modular, prefabricated composite building components using bio-based material systems
    (2023) Zechmeister, Christoph; Gil Pérez, Marta; Dambrosio, Niccolo; Knippers, Jan; Menges, Achim
    Robotic coreless filament winding using alternative material systems based on natural fibers and bio-based resin systems offers possible solutions to the productivity and sustainability challenges of the building and construction sector. Their application in modular, prefabricated structures allows for material-efficient and fast production under tightly controlled conditions leading to high-quality building parts with minimal production waste. Plant fibers made of flax or hemp have high stiffness and strength values and their production consumes less non-renewable energy than glass or carbon fibers. However, the introduction of natural material systems increases uncertainties in structural performance and fabrication parameters. The development process of coreless wound composite parts must thus be approached from the bottom up, treating the material system as an integral part of design and evaluation. Existing design and fabrication methods, as well as equipment, are adjusted to emphasize material aspects throughout the development, increasing the importance of material characterization and scalability evaluation. The reciprocity of material characterization and the fabrication process is highlighted and contributes to a non-linear, cyclical workflow. The implementation of extensions and adaptations are showcased in the development of the livMatS pavilion, a first attempt at coreless filament winding using natural material systems in architecture.
