In a dynamic and evolving society there is a need for temporary and mobile structures. For this, deployable scissor structures - structural mechanisms that can transform from a compact state to a fully deployed configuration - are suitable. However, this transformational capacity complicates the design process since there is a strong interaction between geometry, kinematic properties and structural response. In the conceptual design phase there is a need for more structural insight related to geometric aspects of deployable scissor structures. Toward this end, this research evaluates the influence of design parameters (height, span, structural thickness, number of units, and scissor type) on the structural behaviour (stress, deflection and mass) of scissor arches. A sensitivity analysis is first performed which determines the relative influence of each of these parameters. Then a comprehensive parametric structural study is performed to determine the best values for efficient (low mass) scissor systems. The result of this research is a set of guidelines to facilitate the design of competitive scissor structures and enhance further analysis and realisation. (C) 2015 Elsevier Ltd. All rights reserved.
