The present invention relates to a CFT column having a diaphragm with simple structure due to horizontally welding connection reinforcing bars to flange plates and a portion for joining the same and steel beams using the same, wherein the portion is formed into a structure for rigidly joining the CFT column and the steel beams with definite performances properly using the CFT column. The CFT column according to the present invention is a CFT column having concrete filled therein, and comprises: a steel column; a pair of the flange plates corresponding to the installation directions of the steel beams, facing each other, and horizontally welded to the inner or the outer surfaces of the steel column; and the connection reinforcing bars installed to connect the pair of the flange plates each other and welded to the flange plates by the whole lengths thereof after laid on the flange plates. The structure for rigidly joining the CFT column and the steel beams according to the present invention comprises: the CFT column having the diaphragm in which the connection reinforcing bars are horizontally welded to the flange plates; the steel beams having flanges welded to the flange plates or the steel column at the same level of the flange plates of the CFT flange plates; and the filled concrete filled in the steel column. |
