Reinforced concrete is a major contributor to the environmental impact of the construction industry, due not only to its cement content, but also its steel tensile reinforcement, estimated to represent around 40% of the material embodied carbon. Reinforcement has a significant contribution because of construction rationalisation, resulting in regular cages of steel bars, despite the availability of structural-optimisation algorithms and additive-manufacturing technologies. This paper fuses computational design and digital fabrication, to optimise the reinforcement layout of concrete structures, by designing with constrained layout optimisation of strut-and-tie models where the ties are produced with robotic filament winding. The methodology is presented, implemented in open-source code, and illustrated on beam and plate reinforcement applications. The numerical studies yield a discussion about parameter selection and constraint influence on material and construction efficiency trade-offs. Small-scale physical prototypes up to 50 cm × 50 cm provide a proof-of-concept.

混凝土钢筋的结构设计和制造,包括布局优化和机器人纤维缠绕
钢筋混凝土是建筑业对环境影响的主要贡献者,这不仅是因为其水泥含量,还因为它的钢拉伸钢筋,估计约占材料隐含碳的 40%。由于结构合理化,加固具有重大贡献,尽管有结构优化算法和增材制造技术,但钢筋笼却规则无序。本文融合了计算设计和数字制造,通过对支柱和拉杆模型进行约束布局优化设计,以优化混凝土结构的加固布局,其中拉杆是使用机器人细丝缠绕生产的。该方法以开源代码的形式介绍和实现,并在梁和板加固应用中进行了说明。数值研究讨论了参数选择和约束对材料和施工效率权衡的影响。最大 50 厘米× 50 厘米的小规模物理原型提供了概念验证。
