<p>PROBLEM TO BE SOLVED: To suitably protect a joint portion of a beam supporting a floor slab and a girder, and to suppress damage to the joint portion.SOLUTION: A frame structure 1 includes a beam 5 supporting a floor slab 4, a girder 7 supporting an end 5x of the beam 5 in a web 5c, and a diagonal member 14 connecting an upper flange 5a of the beam 5 and an upper flange 7a of the girder 7 and diagonally arranged with respect to a longitudinal direction D of the beam 5. Even when the upper flange 5a of the beam 5 receives rotational force by a horizontal load acting on the beam 5 from the floor slab 4, the rotational force is transmitted to the girder 7 mainly via the diagonal member 14. Accordingly, the load imparted to a joint portion 10 of the beam 5 and the girder 7 by the rotational force can be suppressed. Especially, the diagonal member 14 is diagonally arranged to the longitudinal direction of the beam 5, and therefore rigidity in the horizontal direction in the junction portion 10 of the beam 5 and the girder 7 can be enhanced.</p> |
