Design and Construction of Spatial Curved Structures Based on Concrete Additive Manufacturing (2026-03)¶

This study confronts core challenges in concrete additive manufacturing (AM) for architectural applications. It specifically addresses the design–fabrication disconnection and absence of regulatory frameworks by proposing a multidisciplinary framework integrating parametric design, structural optimization, and robotic construction. Using a spatially hyperbolic gatehouse as a case study, the study developed a design-to-manufacturing framework with four unified functional modules: printing design, finite element analysis (FEA), material performance regulation, and printing strategy formulation. This system achieves fully digitalized construction of complex curved structures. Additionally, a novel steel–AM concrete hybrid system is introduced, transcending morphological limitations of conventional methods. The framework’s engineering viability is demonstrated through hierarchical printing strategies and sequential installation protocols. Overall, the research provides a systematic solution that bridges algorithmic optimization and physical construction, advancing architectural AM toward intelligent and code-compliant practices.
