はコンクリート・モルタル６が打設されている。As shown in FIG. 1, the steel tube column structure 1 has a steel tube column 2, and the steel tube column 2 is made of steel that forms the outer shape of the column.
It has a. The panel zone 3 portion of the steel pipe 2a to which the beam 5, which will be described later, is attached is a ribbed 11 pipe 2C with ribs 2b formed inside, and the steel pipe 2a portion other than the ribbed steel pipe 2C is a regular pipe without ribs. It is made of steel pipe. Furthermore, beams 5.5 made of H-shaped steel or the like are connected to the panel zone 3 portion from both sides, and concrete mortar 6 is placed inside the steel pipe 2a.

達され、支持される。Since the steel pipe column structure 1 has the above configuration, the adhesion between the concrete mortar 6 placed inside the steel pipe 2a and the steel pipe 2a is due to the ribbed steel pipe 2C provided in the panel zone 3 portion. It is held by the ribs 2b. Therefore, the shear force SF generated in the beam 5 is the ribbed steel pipe 2C
The bearing pressure acting between the rib 2b and the concrete mortar 6 is transmitted to and supported by the concrete mortar 6 inside the steel pipe 2a.
