The Striatus bridge

Abstract The paper describes the physical realisation of a 3D-concrete-printed, mortar-free, unreinforced masonry arched footbridge, designed for disassembly and reuse. also details novel integrated design, engineering fabrication framework manufacturing assembly processes used project. research, motivated by rapid growth in large-scale 3D concrete printing (3DCP), addresses current lack both design tools design-to-production solutions. It is guided insight regarding applicability analysis methods to large-scale, layered with compression dominant materials such as concrete. Thus, underlying computational environment further extends adapts advances structures 3DCP blocks. Adopting an paradigm can make it possible (i) reduce amount allowing precise placement only where needed along compressive flow forces, (ii) steel reducing tensile flexural strength requirements through compression-appropriate global, shape block discretisation, (iii) reuse components, repair recycle more easily. This builds on relevance delivering ecological promises development 3DCP-specific, toolkit.
