With structural members consisting of an I-beam, round bar, square bar, slab element and the like for use in a pillar, beam, pile and the like, plate buckling of the structural member is prevented by restraining a deformation in directions other than the surfaces of the slab element by use of reinforcing members and stable plastic deformation can be obtained even after the structural member is subjected to yielding. The reinforcing member or members are attached to one side or both sides of the slab member to be restrained. The reinforcing member does not substantially share a force produced in the structural member in such a manner that loose holes and bolts are combined together to allow the surfaces in contact with each other to slide on each other, so that the plastic deformation capability of the structural member can be fully displayed. Furthermore, when the reinforcing member gives little influence to the whole strength in such a case that the sectional area of the reinforcing member is small, the reinforcing member or members can be firmly fastened to the structural member by bolts or welding. Particularly, when the structural member is formed of a high tension steel, the yield load is high and the yield strength is decreased abruptly due to occurrence of the plate buckling after the yielding so that the reinforcing construction according to the present invention can prevent the plate buckling, thereby effectively utilizing the plastic deformation capability. |
