Conceptual Design and Experimental Testing of a Deployable Scissor Arch

Prototype of the deployable scissor arch

The project handles the experimental validation of a deployable structure comprised of scissor arches (6 m span, span-to-height ratio of 2). To evaluate the feasibility of the resulting scissor arch designs as the load bearing elements of rapidly deployable shelters, a simple aluminium scissor arch is constructed at full scale.

Subsequently, the structure is subjected to symmetric and asymmetric loading to assess the structural performance using Digital Image Correlation and Tracking. This project represents a benchmarking study, validating a finite element model with experimental results. The novel numerical evaluation methodology offers the potential for future developments in the design and realisation of shelters based on deployable scissor structures.
