Abstract

If we look at the cost intensity of buildings (Lee et al., [2]) and the current demographic and economic developments, the demands for cheap, fast, location-independent, and flexibly adaptable residential and industrial buildings are becoming increasingly clear (Welpe & Grundke, [8]). That brings up the need for some kind of automation, as well as, effective usage of the most popular building material, concrete. The answer can be in prefabrication and optimization. With the development of the technology of concrete 3D printing, the authors’ team project aims to explore the design and production of individual segments (modules), followed by the assembly of the entire shell structure without using formwork. This paper deals with the particular problems of development and segmentation of these designs for satisfying the scalability and adaptability as well as other production conditions. The optimization of material usage lays in constructing/ designing the shapes where the principal force directions are distributed in the direction of shell segmentation. The idea of this research is a constructive design of double curved shell structures for modular 3D concrete printing. The parametrization of construction arcs and algorithm of PQ circular mesh generation (Tellier & Baverel, [7]) that connects them, are defining the modular segments, which are analyzed for calculation. Using methods based on the descriptive differential geometry, for generating meshed shells, this research shows how contemporary architectural designs can be integrated into the demands of 3D concrete production.
