In previous research on the production of free-form concrete panel, most studies have focused on single-curved FCP. Additionally, research has primarily targeted square-shaped FCP rather than polygonal ones. However, when it comes to manufacturing double-curved polygonal FCPs, there is a concern about significant errors in the lower shape. double-curved FCP have multiple directions of curvature progression and frequent changes in surface curvature. Therefore, manufacturing double-curved polygonal FCPs can be challenging in terms of substructure implementation. This study thus investigates the substructure of double-curved polygonal FCPs. Specifically, it involves designing double-curved polygonal FCPs, implementing the corresponding shape in the LSM, and comparing it with the design shape. Experimental results showed significant shape errors in areas with abrupt curvature changes, and inevitable errors occurred in areas where there were previously no errors, despite three rounds of shape corrections. This study attributes these results to the elasticity of the LSM and limitations in deriving rod displacement values. Based on the experimental findings, the study outlines directions for future research. The results of this study are expected to serve as reference material for researchers and professionals in the field of FCP production. Additionally, they are anticipated to be actively utilized as foundational research data for subsequent studies.
