Spatial　cable-truss　structure　without　inner　ring　cables　(SCSWIRC)　is　a　new　cable-truss　tension　structure　(CTTS),　the　features　of　which　are　composed　of　a　series　of　planar　cable-truss　frames　interwoven　with　each　other.　Its　anti-collapse　capacity　is　better,　but　its　construction　forming　is　complex.　The　reasons　are　that　the　strut＇s　number　and　length　will　be　enlarged　with　the　span　increase.　Serious　collision　and　winding　of　struts　occur　during　construction　due　to　SCSWIRC　formed　by　a　series　of　planar　cable-truss　frames　interwoven　with　each　other,　which　cause　many　difficulties　in　construction.　According　to　the　complex　problem　of　construction　forming,　the　segmented　assembly　construction　forming　method　without　brackets　is　proposed　for　SCSWIRC,　and　the　basic　idea　of　the　proposed　method　is　elaborated　in　detail.　The　SCSWIRC＇s　experimental　model　with　a　6m　is　designed,　and　numerical　simulation　and　experimental　research　were　carried　out　on　the　experimental　model.　The　experimental　results　show　that　the　error　range　of　the　internal　forces　of　cables　and　struts　is　6.99%similar　to　11.58%,　and　displacement　errors　of　node　1　and　node　2　are　3.27mm　and　3.81mm,　respectively　verifies　the　feasibility　and　correctness　of　the　proposed　method.　Then　the　static　and　dynamic　experiment　is　carried　out　based　on　the　final　formed　model.　The　static　and　dynamic　experiment　verifies　the　feasibility　of　the　final　formed　model,　which　further　shows　the　rationality　and　correctness　of　the　segmented　assembly　construction　forming　method　without　brackets.　Copyright　(C)　2022　by　The　Hong　Kong　Institute　of　Steel　Construction.　All　rights　reserved.
