BUCKLING STIFFENING STRUCTURE OF H-SHAPED CROSS-SECTIONAL MEMBER AND STEEL-FRAME STRUCTURE
PROBLEM TO BE SOLVED: To allow for suppression of lateral buckling and shear buckling by simple construction even when receiving bending compressive force and shear force by external force.SOLUTION: A beam 3 composed of H-shaped steel is rigidly joined to a column. The beam 3 comprises an upper flange portion 3b and a lower flange portion 3c on both ends of a web 3a. The lower flange portion 3c being a portion where bending compressive force is generated of the beam 3 comprises a steel pipe-shaped stiffening member 6 having a hollow part for enclosing the lower flange portion 3c. One place of the steel pipe-shaped stiffening member 6 is cut in the material axial direction to form a cut portion 6a, the web 3a of the beam 3 is inserted in the cut portion 6a to fit the beam 3 and the stiffening member 6 together, both circumferential-direction ends of the stiffening member 6 are joined to both surfaces of the beam 3 by welding or the like. Studs 8 are fixed at a predetermined interval to the upper flange portion 3b not provided with the stiffening member 6 of the beam 3, and a floor slab 9 and the upper flange portion 3b are integrated via the stud 8.SELECTED DRAWING: Figure 2
【課題】外力による曲げ圧縮力やせん断力を受けても簡単な施工で横座屈とせん断座屈を抑えることができる。【解決手段】Ｈ形鋼からなる梁３は柱と剛結合している。梁３はウェブ３ａの両端に上フランジ部３ｂと下フランジ部３ｃを設けている。梁３の曲げ圧縮力を生じる部分の下フランジ部３ｃに、下フランジ部３ｃを囲う中空部を有する鋼管状の補剛部材６を設けた。補剛部材６は鋼管状の一カ所を材軸方向に切断した切断部６ａを形成して梁３のウェブ３ａに嵌挿し、その周方向の両端をウェブ３ａの両面に溶接等で接合した。梁３の補剛部材６を設けない上フランジ部３ｂにスタッド８を所定間隔で固定し、スタッド８を介して床スラブ９と上フランジ部３ｂを一体化した。【選択図】図２
