120146 - Harnessing Origami Mechanics for Large-Scale Systems That Support Structural Loads 

This talk will give an overview of several important research developments related to structural mechanics that have allowed for transitioning the principles of origami paper folding to large infrastructure-scale applications. As a first step, we discuss the stiffness of origami structures, because high stiffness-to-weigh ratios are necessary to support self-weight and loading on the structure while minimizing the displacement. We present several origami designs with high stiffness including: self-restraining deployable origami tubes; hexagonal dome-like origami; and curved crease corrugations with multidirectional stiffness. To assist with actuation of large-scale origami, we discuss the use of internal pre-stressed springs that counteract gravity to enable efficient motion and ensure stability throughout deployment. Finally, we present a framework for the design and fabrication of large-scale modular origami consisting of thick panels and metallic hinges. These modular origami can fold into practical geometries including walls, columns, and beams; and have the capacity to carry large structural loads. The work paves the way for novel Civil Engineering and Architectural applications of origami including adaptable facades, pre-fabricated modular structures, and reusable infrastructure for shared community use.
