This study presents a novel method for constructing freeform concrete shells, addressing the challenges of traditional methods that rely on heavy, expensive steel formworks. By integrating fabric formworks with geodesic grids, this approach capitalizes on the lightweight, cost-effective, and reusable nature of fabric, while ensuring the necessary structural support through geodesic grids. The design process incorporates form-finding simulations and finite element analysis to optimize the shell’s shape, focusing on the performance of flexible membranes and geodesic grids under various loading conditions. This detailed analysis helps achieve optimal grid configurations for the shell’s curved surfaces. A unique aspect of this technique is the use of elastic grids within the mesh shell, which effectively manage curvature and stress during the shell’s formation. The study emphasizes the importance of geodesic grid configurations in creating adaptable and structurally sound freeform concrete shells. This method marks a significant advancement in concrete construction, enhancing durability and environmental sustainability by reducing material waste and production costs.
