A　new　concept　for　improving　the　robustness　of　pre-stressed　spatial　structures　was　introduced.　The　purpose　of　this　concept　is　to　avoid　existing　key　elements　by　creating　an　alternative　load　path　for　every　structural　member.　With　this　new　concept,　the　Annular　Crossed　Cable-Truss　Structure　was　proposed.　How　to　defining　the　target　geometry,　force-finding,　and　designing　connections　for　the　Annular　Crossed　Cable-Truss　Structure　were　illustrated　by　means　of　designing　an　experimental　set-up.　Feasibility　of　the　structure,　including　self-weight,　structural　stiffness,　and　structural　adaptability　in　asymmetric　load　arrangement,　was　discussed　based　on　experimental　results.　The　results　show　that　the　Annular　Crossed　Cable-Truss　Structure　can　have　a　light　self-weight,　reasonable　structural　stiffness,　and　acceptable　adaptability　in　asymmetric　load　arrangement.　It　is　concluded　that　the　Annular　Crossed　Cable-Truss　Structure　is　a　feasible　pre-stressed　spatial　structure.
