Supporting data for “Bio-inspired structural design of 3D printed strain-hardening cementitious composites (SHCC)”

<p dir="ltr">Owing to their exceptional performance, natural biological structures have inspired the development of artificial materials. However, their complexity often exceeds that of traditional manufacturing capabilities. The high design flexibility of 3D concrete printing (3DCP) makes it a promising method for the fabrication of bio-inspired structures. Strain-hardening cementitious composites (SHCC) are recognized for their strength, ductility, toughness, and durability, making them suitable for 3DCP. Inspired by the diving bell of <i>Argyroneta aquatica</i>, we developed a 3D printed SHCC reticulated shell roof that exhibited high ductility, low weight, and high energy absorption. We proposed and validated the construction of an almost fully automated building with this bio-inspired 3D printed SHCC reticulated shell roof. Inspired by the slender stems of <i>Elytrigia repens</i>, we developed a novel bio-inspired 3D printed SHCC porous lattice structure. This structure was optimized at both the micro- and macroscales, focusing on lightweight construction, material efficiency, and cost savings without compromising mechanical performance. The structure can be applied to building facades, offering both aesthetic appeal and material efficiency, as well as partition walls that provide excellent insulation and soundproofing properties. This study provides a theoretical foundation and practical insights for the development of bio-inspired 3D printed concrete structures.</p>
