Abstract：

In　order　to　study　the　static　stability　of　an　aluminum　alloy　single-layer　spherical　reticulated　shell,　a　static　loading　test　of　a　K6　reticulated　shell　with　3　rings,　a　4　m　span,　and　a　1/7　height-to-span　ratio　is　carried　out.　The　deformation,　internal　force　distribution,　and　failure　mode　of　the　reticulated　shell　model　are　discussed.　By　comparing　the　monotone　tensile　test　and　simulation　of　the　single　member,　the　simulation　method　of　rivet　used　in　the　finite　element　model　(FEM)　is　obtained,　and　the　bending　stiffness　and　axial　slip　stiffness　of　gusset　joints　are　calculated.　Considering　the　joint　stiffness　in　the　FEM,　the　simulation　results　and　the　test　fit　well,　indicating　that　the　influence　of　the　joint　stiffness　on　the　static　stability　of　the　reticulated　shell　cannot　be　ignored.　In　addition,　by　comparing　the　effect　of　different　parameters　of　joint　stiffness,　the　axial　slip　stiffness　should　be　considered　in　the　stability　design　of　reticulated　shells.　©　2024　Elsevier　Ltd
