The　seismic　behavior　of　Z-shaped　joints　connecting　H-section　beam　and　L-shaped　concrete-filled　steel　tubular　column　for　prefabricated　steel　structures　were　studied.　The　ABAQUS　finite　element　model　was　established　and　validated　based　on　the　joint　test　results.　The　load-displacement　curves,　skeleton　curves,　failure　mode　and　performance　indicators　of　the　joint　were　obtained　by　finite　element　analysis.　According　to　the　finite　element　results,　adding　web　splice　plates,　increasing　the　beam　section　height　or　decreasing　the　distances　between　the　outmost　bolts　and　the　splicing　zone　center　can　increase　the　yield　load　and　peak　load　of　the　joints.　Increasing　the　bolt　number　on　the　flange　can　improve　the　slip　load　of　the　joint,　but　may　reduce　the　ductility　performance.　Increasing　the　overhang　distance　of　cantilever　beam　can　improve　the　slip　load,　yield　load　and　peak　load,　and　reduce　the　required　bolt　number　for　the　flange　connection.　Based　on　the　finite　element　results,　the　reliability　of　the　calculation　formulas　for　the　joint　flexural　capacity　and　ultimate　flexural　capacity　is　verified.　Copyright　©2022　Engineering　Mechanics.　All　rights　reserved.
