Fabrication-aware Parametric Design of Segmented Concrete Shells

Research is underway to explore the potential of using structurally efficient non-prismatic geometries to substantially reduce the amount of concrete in building elements, thus reducing their carbon footprint. In particular, the benefits of using thin concrete shells for floor slabs are being quantified, by automating their production using computational design and digital fabrication methodologies. This paper presents the current development of a computational framework for the design of thin concrete shells, which incorporates existing solutions for parametric modelling, finite element analysis, isogeometric analysis and optimisation where appropriate. By incorporating fabrication constraints in the design optimisation, and by making it easy and quick to use, our approach aims to transform the construction industry towards a more sustainable future.
