惧れがなくなる。(Effect of the Invention) As described above, the rectangular steel pipe concrete member according to the present invention has a spiral stirrup or a lengthwise portion in the rectangular steel pipe excluding at least a part of the joint with the beam. Since it is arranged by connecting with auxiliary reinforcement without using the main reinforcement so as to maintain the space between the ring reinforcements, and the square steel pipe is filled with concrete, it is a high compression force part due to bending and axial force. The deformation of the rectangular steel pipe is prevented, and the proof stress of the member is increased.Thus, the rectangular steel pipe concrete member according to the present invention has a smaller cross-section than the conventional rectangular steel pipe concrete member, and is a tough member. Further, the plate thickness of the rectangular steel pipe can be reduced. It can also be applied to super high-rise buildings. Furthermore, the auxiliary bar without using the main bar so as to maintain the interval of the spiral bar or the ring bar at the longitudinal direction excluding at least a part of the joint with the beam in the rectangular steel pipe or the longitudinal end. Since the main reinforcements largely project to the beam joints, there is no fear that the columns, beams, and main reinforcements will be congested at the joints and the workability will be deteriorated.
