Cable-truss　tensile　structures　are　one　of　the　most　imperative　types　of　spatial　structures,　and　a　spatial　cable-truss　structure　without　inner　ring　cables　(SCSWIRC)　is　a　new　type　of　cable-truss　tensile　structure.　Although　SCSWIRC　has　a　strong　anti　-collapse　capacity,　its　construction　forming　is　difficult.　Based　on　the　concept　of　grid-jumped　layout　for　struts,　the　experimental　model　with　a　span　of　6　m　is　designed,　and　then　three　grid-jumped　layout　schemes　are　proposed　to　simplify　structure　system.　The　static　and　dynamic　properties　of　experimental　and　finite　element　models　are　systematically　studied.　The　results　show　that　experimental　values　agree　with　simulation　values.　The　errors　of　the　static　experiment　are　in　the　range　of　6%similar　to　11.53%　and　the　errors　of　the　dynamic　experiment　are　in　the　range　of　5%similar　to　8%.　The　grid-jumped　layout　has　negligible　effects　on　the　internal　forces　of　cables.　However,　it　has　excellent　effects　on　the　internal　forces　of　struts　and　nodal　displacements　at　the　grid-jumped　layout,　so　the　mechanical　property　of　struts　needs　to　be　rechecked　after　grid-jumped　layout.　The　mechanical　property　of　the　optimal　grid-jumped　layout　scheme　does　not　change　compared　with　original　scheme.　The　optimal　grid-jumped　layout　scheme　not　only　simplifies　SCSWIRC,　but　also　reduces　the　amount　of　steel.　The　study　can　promote　the　application　of　SCSWIRC　in　practical　engineering.　Copyright　(c)　2022　by　The　Hong　Kong　Institute　of　Steel　Construction.　All　rights　reserved.
