PURPOSE:To eliminate the need for welding as well as to raise the bending and shearing resistances and deformation performance of the joint structure by a method in which connecting steel members are inserted into through holes of the side wall of a steel tube, and concrete is placed into the steel tube for fixation. CONSTITUTION:Through holes 4 are formed in the side wall of a steel tube 1, and one ends of connecting steel members 3 consisting of iron bars are inserted into the steel tube 1 and fixed with filling concrete 5. The other ends of the connecting steel members 3 are fixed to footing concrete 2. Therefore, the need to connect the steel tube 1 with the connecting steel members 3 by welding is eliminated, and bending moment and shearing force on the connections are transmitted in terms of the drawing and shearing resistances of the connecting members. Since the flow of the force is directed from the connecting steel members 3 to the steel tube 1 by friction with the concrete in the wall face of the steel tube 1, no stress concentration occurs as compared with the case of the conventional welded structures. |
