Curve-folded form-work for cast, compressive skeletons

The research described in this paper explores the synergy between the methods of form-finding (for funicular loads) with curved-crease folding(CCF). The paper will propose a two-step process that combines a form-finding method that finds the form under vertical loading and with a mesh-perturbation method that solves for planarity and developability constraints. The resulting geometry will be shown to be amenable to construct curve-crease folded moulds for concrete casting. The paper will also describe the design of a demonstrative prototype - a self-supporting structure composed of bar-elements that are formed by casting concrete into molds that are curve-folded from sheet material.
