Abstract

Nature, one of the biggest sources of inspiration for civil engineering design, exhibits thin-walled shell structures among a wide range of organisms. Due to membrane stresses that ideally prevail in such thin-walled structures, shells have an extremely favourable span-to-material ratio that in turn means excellent structural performance. The approach of looking towards nature for inspiration can be simplified by considering crystallographic symmetries, which also appear in nature and give rise to a method for creating shell structures carrying an additional topological interlocking property. The aim of the joint research project CRC/TRR 280 [1] is to achieve equivalent performance in shell structures made of textile reinforced concrete (TRC). Figure 1 illustrates the project's main concept, by showing how similar, after appropriate processing, the TRC structures can be to naturally occurring shell structures. Consequently, processing in all generality is the main focus of the project. The way how to design, optimize, and, of course, how to produce such bioinspired structures from TRC with the appropriate accuracy to match required design properties gives rise to many challenges to be overcome within the duration of the project. For the purpose of design and optimization of the structures mentioned above, it was necessary to establish a reliable data flow for the realization and generation of the geometrical data. Multiple software environments were used as a platform for the creation and assembly of the computational routines that, using principles and methods of generative design, aim to find an efficient TRC shell solution according to the required architectural and structural constraints.
