In　order　to　study　the　seismic　behavior　of　bent　frame　column　in　vertical　frame-bent　structure,　some　representative　components　of　a　vertical　frame-bent　structure　were　selected　as　the　research　objects　and　the　quasi-static　test　of　a　scaled　model　and　ABAQUS　analysis　were　conducted.　The　study　focused　on　the　failure　patterns,　hysteretic　characteristics,　ductility,　energy　dissipation　capacity　and　inter-story　drift　ratio　of　the　specimen.　On　this　basis,　the　seismic　performance　of　bent　frame　column　under　different　slenderness　ratios　and　axial　compression　ratios　were　studied　according　to　numerical　simulation.　Results　show　that　the　main　failure　mode　of　the　specimen　is　bending　failure,　which　occurs　at　the　bottom　of　bent　frame　column.　The　horizontal　bearing　capacity　is　obviously　different　under　loading　in　different　directions　with　significant　eccentricity.　The　ductility　and　energy　dissipation　capacity　reduce　significantly　with　the　increase　of　slenderness　ratio　and　axial　compression　ratio　of　bent　frame　column.　It　is　suggested　that　the　slenderness　ratio　should　be　less　than　45　and　the　axial　compression　ratio　should　be　less　than　0.2.　©　2017,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
