Vertex pavilion: deployable arches structure with triangular section

Abstract

The research study presented in this paper focused on the potential of scissor-like deployable structures with straight bars to create compact, light and cost-effective solutions for temporary shelters and emergency architecture. The design and construction process included parametric design; various scale model prototypes and a final 1:1 scale prototype. The ‘Vertex’ structure is comprised of three triangles made up of 27 scissor-like straight bars. When unfolded the triangles scissor-like bars deploy to create three arches. The arches are joined to each other at ground level and secured in place using three bases. Finally, the arches’ stability is secured at the upper level by the tension force of the textile membrane. The fabrication process included both conventional fabrication and assembly of materials as well as the use of 3D printing and laser cutting technology. The assembly of the 1:1 prototype was carried out in one hour. Each triangle weights 9 kg, and the entire structure including the bases and the textile is 70kg. The prototype was fabricated and tested by the MArch Architecture students and Lab at Nottingham Trent University, as part of a workshop on deployable structures conducted by the SMiA (Structural Morphology in Architecture) Research Group.
