    Nature-inspired generation scheme for shell structures
    (2012) La Magna, Riccardo; Waimer, Frédéric; Knippers, Jan
    Although less researched and put into practice in the building environment, pure plate structures are to be observed frequently in biological structures. The 3-plate principle which is common in the morphology and growth pattern of natural systems is also found to be of a structurally optimum content when considered from a plate point of view. This is for instance the case of the sea urchin’s plate skeleton morphology, which served as biological inspiration for the recently built ICD/ITKE Research Pavilion 2011 at the University of Stuttgart. The current paper will focus on the 3-plate principle and its mechanical features, also presenting study models to analyse the structural characteristics and advantages of the principle. Along with the theoretical background, the paper will introduce the structural concept of the pavilion, as well as the analysis methods used for its design and engineering.

    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.
