| Popis: | Tensairity is a new lightweight structural concept. It is a synergetic combination of struts and cables stabilized by a membrane, which is inflated by low pressurized air. The outcome of this interaction between the different elements is a structure with the load bearing capacity of conventional steel girders and the low weight of an air beam. The innovative concept Tensairity provides moreover features few conventional structures have, such as a fast assembling/dismantling, and a compact storage and transport volume. This technology has obvious a great potential for temporary and mobile architectural applications. However, improvements and adaptations to the structural concept have to be identified to make the Tensairity concept suitable for deployable applications. After all, a basic Tensairity girder can not be folded or rolled together without disassembling the different parts it is constituted of. A foldable Tensairity structure is developed and investigated experimentally in this research. The influence on this promising mechanism - called 'the foldable truss' - of different parameters such as the amount of hinges and the presence of pretensioned cables, is studied and discussed. The results are summarized and will then provide the basis for further research for a proposal of an optimised deployment mechanism for the deployable Tensairity structure. |
