PROBLEM TO BE SOLVED: To facilitate the manufacture of segments without requiring a high welding technique and dimensional precission of members by connecting a main girder to a joint plate through the wing plate of a T-shaped joint member. SOLUTION: In the steel segment 1, a rectangular parallelepiped opened at one end is constituted of side plates 2, a joint plate 3, and a skin plate 4 connected to the lower end face of the side plates 2 and the joint plate 3. Main girders 5 and vertical ribs 6 are disposed in the inside of the rectangular parallelepiped. The main girders 5 is provided with T-shaped joint members 7 at both ends of the main girder body 8 and the legs 10 thereof are fixed by full penetration welding and the wing plates 12 of the T-shaped joint members 7 are only attached to the inside face of the joint plate 3 made of a thin steel plate to connect both members. The vertical ribs 6 are disposed at right angles against the main girders 5. As the T-shaped joint member 7 may be brought into contact with the joint plate 3 or may be temporarily welded therewith, dimensional inaccuracy is hard to arise in respective members when assembling the segments 1 and a high skillfulness to cope with the jointing work is not required.
