Abstract
Fabric and ice shells, first pioneered by Heinz Isler, are lightweight structural systems that allow for inexpensive and reversible construction of free-standing stiffened shell structures. They are of interest for exploring new structural forms and construction methods and are analogs for shells built with more permanent materials. This paper reflects on the design and construction of a fabric and ice shell (6.6mx11.5mx3.6m), called Fabrigami, built in Winnipeg, Canada in January 2016. The project introduces a new formal and structural typology for fabric-based shell structures, taking inspiration from origami and folded plate structures but also utilizing the curved geometry of stretched fabric for added structural stiffness. The paper includes a detailed discussion of the design process, structural behaviour, fabrication, construction, and the resulting performance of the completed shell structure, and concludes with an assessment of how this temporary structure's innovations could be used for permanent buildings in the future.
