Recent Development of Deployable Tension-Strut Structures

摘要

This paper presents the latest development of Deployable Tension-StrutnStructures (DTTSs), which can be assembled quickly to save construction time whilenthe structural efficiency is maintained to be as good as that of conventional doublelayernspace frames. Pre-tensioning techniques are used to enhance the structuralnstiffness and stability of the structure after it is “locked” to its final configuration. Thendesign concept is explained in details with four illustrative examples and the structuralnefficiency of the proposed systems is investigated by using advanced non-linearnanalysis and free-vibration analysis. Novel moveable pin-jointed system has beenndeveloped to allow deployment of the tension-strut structures. Full scale prototype isnbuilt to demonstrate the buildability and deployability of the proposed systems. Thenresults conclude that the proposed structures are structural effective, lightweight andncan be easily deployable for spatial enclosure.
