| Abstract: | In this paper,four beam-column endplate joint specimens of concrete-filled thin-walled steel tube frame with ribs were tested under static loading.The end of the high strength bolt is welded with 50 mm long deformed rebar.The steel tube of the column is composed of the cold-formed thin-walled steel members with 1.5 mm or 3.0 mm thickness.The endplate type and the thickness of column were investigated to study the failure modes and moment-rotation relationships of the connections.Bending capacity,stiffness,d... |
