PROBLEM TO BE SOLVED: To provide a steel beam having a floor slab installed continuously on one side in a horizontal direction orthogonal to a material axis direction and over a studded flange, the steel beam structure being capable of suppressing a cone-shaped destruction of concrete of the floor slab around the stud and preventing sudden load reduction even when a cone-shaped destruction takes place.SOLUTION: A steel beam 1A has both ends connected rigidly to a column 11 and a plurality of studs 3, 3...disposed in a row on an upper part of an upper flange (flange) 2 in a material axis direction, and a floor slab 4 is installed continuously on one side in a horizontal direction orthogonal to the material axis direction and over the upper flange 2. A reinforcing member 5A anchored on concrete 41 of the floor slab 4 is connected to the upper flange 2.SELECTED DRAWING: Figure 2 |
