A　novel　prestressed　high-strength　bolt　(PHSB)　joint　applied　in　the　prefabricated　large-span　ridge　tube　cable　dome　with　annular　struts　(PLRTCDAS)　was　proposed.　Firstly,　the　hysteretic　behavior　of　the　PHSB　joint　under　combinations　of　bending　moment　and　axial　compression　was　studied　by　experiments.　Four　parameters　of　the　PHSB　joint,　including　the　disc　thickness,　perforated　cross　plate　thickness,　perforated　angle　steel　thickness,　and　outer　sleeve　height,　were　considered　in　the　test.　The　effects　of　these　parameters　on　the　hysteretic　curves,　skeleton　curves,　bearing　capacity,　failure　modes,　energy　dissipation　behavior,　and　ductility　were　analyzed　and　discussed　in　detail.　Secondly,　a　three-dimensional　finite　element　(FE)　model　of　the　PHSB　joint　considering　geometric,　material,　and　interaction　nonlinearities　was　established　by　ABAQUS.　The　accuracy　of　FE　model　was　verified　by　comparing　the　test　and　numerical　results.　Finally,　the　hysteretic　behavior　of　the　PSHB　joint　under　different　combinations　of　axial　forces　and　bending　moments　was　investigated　by　the　proposed　FE　model.　The　research　indicates　that　the　PHSB　joint　exhibits　perfect　energy　dissipation　capacity　and　higher　ductility.　Reducing　the　perforated　angle　steel　thickness　or　increasing　the　outer　sleeve　height　can　improve　the　hysteretic　behavior　of　the　PHSB　joint　without　significantly　reducing　its　bearing　capacity.　The　verified　FE　model　is　an　effective　method　to　simulate　PHSB　joint　hysteretic　behavior.
