BUCKLING STIFFENING STRUCTURE AND SHAPE STEEL
PROBLEM TO BE SOLVED: To provide a buckling stiffening structure and shape steel for restraining an expansion width of a plate element formed of a predetermined cross-sectional shape, and improving local buckling strength.SOLUTION: A buckling stiffening structure 1 of applying the present invention is provided in a plate element formed in a predetermined cross-sectional shape, and comprises an intermediate plate element 2 of continuing in the width direction X in a cross-sectional shape and a pair of side part plate elements 3 for extending by bending from both side parts 20 in the width direction X of the intermediate plate element 2. The pair of side part plate elements 3 are formed by mutually extending in the substantially same direction from both side parts 20 in the width direction X of the intermediate plate element 2, and the direction of extending the pair of side part plate elements 3 more than a virtual straight line S of connecting both side parts 20 in the width direction X of the intermediate plate element 2, becomes the inside direction α. The intermediate plate element 2 forms an inclined part 4 of inclining in the inside direction α by continuing from both side parts 20 in the width direction X, and a rib part 5 projecting toward the outside direction β of becoming the opposite side in the inside direction α from the inclined part 4, is formed in an intermediate part 21 in the width direction X.SELECTED DRAWING: Figure 6
【課題】所定の断面形状で形成された板要素の展開幅を抑制するとともに、局部座屈強度を向上させた座屈補剛構造及び形鋼を提供する。【解決手段】本発明を適用した座屈補剛構造１は、所定の断面形状で形成された板要素に設けられるものであり、断面形状で幅方向Ｘに連続する中間板要素２と、中間板要素２の幅方向Ｘの両側部２０から屈曲して延びる一対の側部板要素３とを備える。一対の側部板要素３は、中間板要素２の幅方向Ｘの両側部２０から互いに略同一の方向に延びて形成されて、中間板要素２の幅方向Ｘの両側部２０を結んだ仮想直線Ｓよりも一対の側部板要素３が延びる方向が内側方向αとなる。中間板要素２は、幅方向Ｘの両側部２０から連続して内側方向αに傾斜する傾斜部４が形成されるとともに、傾斜部４から内側方向αの反対側となる外側方向βに向けて突出するリブ部５が幅方向Ｘの中間部２１に形成される。【選択図】図６
