CFST-RC　column　is　modified　from　CFST　laced　column　in　which　CFST　members　are　connected　with　RC　web　instead　of　steel　bracings.　The　CFST-RC　column　has　excellent　static　and　earthquake　resistant　properties,　such　as　high　strength,　high　ductility　and　large　energy　absorption　capacity.　The　failure　of　CFST　laced　column　is　ductile;　the　cracks　initiate　from　RC-web　and　the　column　fails　due　to　the　formation　of　plastic　hinge　at　bottom　of　CFST　limbs.　Lateral　load　carrying　capacity　increases　with　the　increase　in　the　diameter　of　steel　tubes　and　the　thickness　of　RC-web.　Ductility　increases　with　increase　in　the　diameter　of　steel　tubes　and　decreases　with　increase　in　the　thickness　of　RC-web.　Under　cyclic　loading,　the　hysteretic　performance　of　CFST-RC　columns,　such　as　failure　modes,　ductility,　load　displacement　hysteretic　curves,　energy　absorption　capacity,　strength,　stiffness　degradation　and　load　strain　curves　are　studied　in　this　paper.
