Analysis, Simulation and Implementation in Architecture’, the authors work in an interdisciplinary team composed of biologists, structural engineers, and textile engineers developing novel technical branchings as structural elements for architecture inspired by branchings in nature. Branchings are common in structures of plants and construction and have to fulfill structural demands in both fields. As resource efficiency is a vital factor allowing plants to resist competitive stress, beneficial load-bearing principles found in plants might, in an abstracted manner, also improve technical support constructions. To discover these principles, the biomechanics of selected plant branchings were investigated by FE-simulations. The observed principle of continuous fiber courses from the stem into the branch yields stiff and strong connections also favored in artificial joints. The key challenge is to produce technical branchings with a continuous fiber arrangement. This is enabled by a newly developed braiding process for branched structures. The design of the branched large-scale demonstrator at the Museum of Natural History in Stuttgart for the exhibition ‘baubionik’ (construction-bionics) reveals the potential for future architectural applications with individually variable knot geometries. The findings of the investigation mark a starting point for a novel braided concrete-fiber-reinforced plastic composite construction for branched supporting columns with both high aesthetical and load-bearing demands as a potential competitor for current construction methods of cast steel knots or labor-intensive welded steel pipe joints.
