CONCEPTUAL AND STRUCTURAL DESIGN OF RECONFIGURABLE JOINTS FOR LIGHTWEIGHT SPATIAL STRUCTURES

Abstract Reconfigurable structures enable adaptable spatial configurations in temporary and deployable buildings. A key challenge is designing joints that allow controlled motion during transformation and sufficient strength when locked. This study presents the conceptual and structural design of a novel reconfigurable joint developed for a lightweight, redeployable pavilion. The joint features a solenoid‐actuated spring ‐ loaded Gripping Pins assembly engaging with perimeter cavities to ensure shear continuity in the locked state. A nonlinear finite element model was developed to assess the joint's behavior under representative design loads. Mesh convergence studies were performed and a bilinear material model was used to capture localized yielding. Results show stable global behavior but reveal localized stress concentrations near or above the material's tensile strength in some components, indicating the need for geometric adjustments. The study provides a foundation for future experimental testing, joint optimization and full‐system simulations.
