The invention discloses a novel connecting structure of a steel pipe tie bar. A connecting notch matched with the thickness of a connecting plate (2) is formed in the end of the steel pipe tie bar (1), and the supporting face of the connecting notch and the connecting plate (2) are located on the same horizontal plane. A stiffening rib (4) parallel to the connecting plate (2) is welded to a profile steel column (5). One end of the connecting plate (2) is inserted into the connecting notch in the end of the steel pipe tie bar (1). The connecting plate (2) and the connecting notch are welded in a double-face angular welding mode. A bolt hole is formed in the stiffening rib (4). The other end of the connecting plate (2) is fixed to the stiffening rib (4) through a bolt (3). The connecting plate (2) is welded to the stiffening rib (4) in a fillet weld mode. According to the novel connecting structure of the steel pipe tie bar, a seal plate adopted for the end of a conventional rigid tie bar is omitted, the use am
