DESIGN METHOD OF STEEL BEAM
To provide a design method of a steel beam in which a through hole does not interfere with a steel beam end reinforcement member (a first reinforcement member) and in which a through hole size is not restricted.SOLUTION: An upper side equivalent width-thickness ratio of stiffeners 51, 52 (first reinforcement members) and a lower side equivalent width-thickness ratio of the stiffeners 51, 52 in a web 4 respectively satisfy a required width-thickness ratio condition of the web 4. A length dimension of the stiffeners 51, 52 and a range where the stiffeners 51, 52 are installed are set so that a setting moment of a part where the stiffeners 51, 52 are provided in a steel beam 1 is larger than a local buckling limit strength of a part where the stiffeners 51, 52 are not provided in the steel beam 1. A shear margin of a part where the stiffeners 51, 52 are not provided in the web 4 is set to be equal to or larger than 1.29.SELECTED DRAWING: Figure 1
【課題】貫通孔が鉄骨梁端補強部材（第１補強部材）と干渉しないとともに、貫通孔のサイズが制限されない鉄骨梁の設計方法を提供する。【解決手段】ウェブ４におけるスチフナ５１，５２（第１補強部材）の上側の等価幅厚比およびスチフナ５１，５２の下側の等価幅厚比それぞれが、必要となるウェブ４の幅厚比の条件を満たし、鉄骨梁１におけるスチフナ５１，５２が設けられる部分の設計用モーメントが、鉄骨梁１におけるスチフナ５１，５２が設けられない部分の局部座屈限界耐力よりも大きくなるようにスチフナ５１，５２の長さ寸法およびスチフナ５１，５２を設置する範囲を設定し、ウェブ４におけるスチフナ５１，５２が設けられない部分のせん断余裕度が１．２９以上となるように設計する。【選択図】図１
