Stability Analysis of Vault Prototype Realized by Additive Manufacturing
摘要
Recent interest in masonry structures has highlighted their enduring potential as good solutions in architecture and engineering. The growing focus on the analysis of ancient masonry vaults, constructed globally throughout history, has revived the need to consider these structures for the roofing of new sustainable and innovative buildings. Concurrently, the stability of both ancient and modern masonry vaults remains a compelling and vital area of research [1–8]. This paper examines funicular structures to facilitate a comparative analysis aimed at identifying the optimal shape for hole configurations. The primary objective is to develop a form-finding design for latticed masonry shells, starting from a defined topology and producing an optimized grid concerning stiffness and stability [8–11]. The vault shapes are achieved by adjusting key parameters, such as the lowering degree and the hole pattern within the vault [1, 2]. Comprehensive structural stability analysis for these structures must be conducted across different loading scenarios and constraint conditions [12–14]. In this study, a scaled prototype of the proposed vault typology is fabricated using additive manufacturing techniques. Experimental and numerical tests are performed to correlate numerical predictions with empirical data, thereby enhancing the understanding of the vault’s behavior under load.
