    Design of prestressed gridshells as smooth poly-hypar surface structures
    (Elsevier, 2021) Cao, Ting; D'Acunto, Pierluigi; Castellón, Juan José; Tellini, TelliniAlessandro; Schwartz, Joseph; Zhang, Hong
    This article demonstrates the design potentials of a recently developed approach for generating smooth poly-hypar surfaces, freeform surfaces made of combinations of hyperbolic paraboloids (hypars). In a smooth poly-hypar surface, the double curvature of the individual hypar modules and the smooth connections between them ensure global bending-free structural behaviour. In this article, the structural analysis of a prestressed gridshell as a smooth poly-hypar surface is introduced. Graphic statics is used to evaluate and control the distribution of internal forces within the structure. Moreover, a case study, the Hypar Pavilion, is presented as a prestressed gridshell as a smooth poly-hypar surface structure. The Hypar Pavilion was prefabricated using lightweight materials and low-tech manufacturing techniques. The entire gridshell was manually built out of forty individual hypars, which were combined following a specific sequence to ensure the kinematic stability of the ongoing construction without scaffolding.

    Urban Agriculture Research Center: Innovate & Reconnect
    (2024-04-18) Gil Rivas, Dante R; Castellón, Juan José; Finley, Dawn
    Food is the common thread that binds us all. People once had a direct connection and understanding of the intricate process of farming. Today, urbanization, technology, and the complex web of transportation logistics have obscured our understanding of this process. Many consumers only encounter food in commercialized institutions as finished products, often unaware of its origin or the technologies and dedicated individuals responsible for bringing it to our tables. The thesis explores a crucial but undervalued program typology that plays a role in our everyday lives behind the scenes: agriculture research labs. This exploration focuses on the role of agriculture research scientists and their invaluable contributions to society. The importance of these labs and the scientists' work is that they find new and innovative solutions to agricultural problems. The thesis questions how architecture can bridge the gap between people, scientists, food knowledge, and emerging technologies. The design proposal focuses on improving the quality of the spaces for the researchers while providing a dynamic learning environment for the general public.
