摘要： PROBLEM TO BE SOLVED: To provide required dimensional precision and effective tensile performance by providing an L-shaped reinforcing member butted to the connection part of a main girder and a joint plate from the inside, and connecting the L-shaped reinforcing member to the main girder by fillet welding. SOLUTION: This steel segment is formed of a main girder 3a, a joint plate 5, an L-shaped reinforcing member 12, a vertical rib 4, and a skin plate 6. The fillet weld 17 between the main girder 3a and the L-shaped reinforcing member 12 may be performed only in a sectional area necessary for transmitting the load of the main girder 3a. The fillet weld 17 between the outer main girder 3a and the L-shaped reinforcing member 12 is performed in the axial direction of the outer main girder 3a and in the axially right-angled direction of the main girder 3a. Therefore, since the load of the outer main girder 3a is transmitted to the adjacent segment through the L-shaped reinforcing member 12, sufficient resistant force can be provided to tensile force, and this segment is conformable even to the state where the tensile force by internal hydraulic pressure acts thereon. Accordingly, high tensile yield strength and rigidity can be provided, and the segment can be manufactured with high working precision.
