The　threaded-sleeve　connection　(TSC)　is　a　new　type　of　connection　proposed　for　space　grid　structures　in　view　of　simplifying　the　erection.　The　bending　performance　of　connections　is　important　in　single　layer　space　grid　structures.　In　order　to　study　its　bending　performance,　experiment　were　carried　out　considering　two　load　conditions,　the　pure　bending　and　the　bending　with　shear　force.　The　finite　element　analysis　(FEA)　of　specimens　was　performed　by　means　of　ANSYS.　Through　the　comparisons　on　moment-rotation　curves　and　contact　status,　it　is　verified　that　the　FEA　method　provides　a　reasonable　estimation　of　the　practical　behavior　of　TSC.　Finally,　based　on　this　FEA　method,　the　effect　of　axial　force　and　shear　force　on　the　bending　performance　was　analyzed.　©　2019　by　Siyao　Li,　Xiongyan　Li,　Suduo　Xue,　Chen　Yao　and　Renjie　Liu.
