Investigation into possible geometrical configurations for scissor-type deployable structures using expandable bars

The current paper describes a spin-off investigation from the initially published international research project [1] [2] , which is looking into the design and development of single-meridian grid deployable structure. As a part of the collaborative international project between South Korea (Project Leader), Japan and Denmark, expandable bars of two degrees of freedom (1 x translational and 1 x rotational) were developed to achieve the geometrical compatibility of the single-meridian grid deployable system. The objective of the current research is to investigate the further applications of the expandable bars for creation of dynamic three-dimensional (3D) space using scissor-type deployable system. The research starts with the detail design and prototype construction of the expandable bars in collaboration between the Royal Danish Academy, School of Architecture in Denmark and School of Civil Engineering in Southeast University in China. The construction of the expandable bar, including the material choice, assembly method, and the construction procedure are described in this paper. The paper describes the relationship between the number of the expandable bars in scissor system and resultant geometrical configurations of the structure in 2D space
