PROBLEM TO BE SOLVED: To provide a steel box girder joined to a concrete floor slab at a lower cost than conventional ones without degrading slip preventing performance. SOLUTION: The steel box girder 10 includes an upper flange 12; a lower flange 16; two webs 14 arranged with a predetermined space between the upper flange 12 and the lower flange 16 to form side faces; and a T-shape steel 18 provided on the upper face of the upper flange 12 in the longitudinal direction of the upper flange 12. A flange 18A of the T-shape steel 18 is provided with protrusions 18B, and the lower face of the upper flange 12 is not provided with reinforcing ribs. COPYRIGHT: (C)2011,JPO&INPIT
