Pseudo-static　tests　on　8　steel　columns　with　T-section　models　of　1:2　geometrical　scale　and　equal　stress　under　cyclic　loading　were　reported.　The　deformation　properties,　failure　mode　were　discussed,　and　the　hysteretic　loops,　skeleton　curves,　bearing　capacity,　ductility　and　energy-dissipation　were　investigated.　As　a　result,　the　effect　of　flange　width-thickness　ratio,　web　depth-thickness　ratio　and　axial　compression　ratio　were　reviewed.　Testing　results　indicate　that　the　steel　specially　shaped　column　with　T-section　has　excellent　bearing　capacity,　good　ductility　and　energy　dissipation　if　certain　flange　width-thickness　ratio,　web　depth-thickness　ratio　and　axial　compression　ratio　conditions　are　appropriate.　Finite-element　analysis　were　conducted　based　on　initial　geometric　imperfection　and　geometric　nonlinearity,　and　the　results　were　close　to　those　from　the　tests.　The　typical　failure　mode　was　local　buckling　instability　with　sufficient　plastic　deformation.　Study　evidence　shows　that　steel　specially　shaped　columns　with　T-section　can　be　used　in　buildings　in　seismic　regions.　This　study　can　provide　background　for　practical　engineering　applications　and　design　specification　for　steel　structures　with　specially　shaped　columns.
