Bolted　drum-shaped　spherical　shell　joints　(BDSSJs)　represent　a　type　of　joint　applicable　to　space　grid　structures.　These　joints　merge　the　benefits　of　both　bolted　spherical　joints　and　welded　hollow　spherical　joints,　embodying　features　such　as　a　compact　size,　favorable　centerline　alignment　with　members,　a　high　degree　of　adjustability,　and　high　installation　efficiency.　Through　unidirectional　axial　compression　tests　on　specimens　of　BDSSJs,　this　study　examines　the　stress　distribution,　force　transmission　pathways,　ultimate　bearing　capacity,　and　failure　modes　of　the　joint,　thereby　determining　its　bearing　capacity　and　presenting　a　bearing　capacity　calculation　formula　for　such　joints.　By　establishing　a　finite　element　model　with　parameters　identical　to　the　experimental　specimens,　this　study　analyzes　the　force　and　deformation　of　BDSSJs　under　unidirectional　compression,　identifying　the　high-stress　areas　during　the　compression　process　of　BDSSJs.　The　findings　of　this　study　provide　a　basis　for　the　practical　engineering　application　of　such　joints,　as　well　as　theoretical　support　for　subsequent　dynamic　performance　into　BDSSJs.
