STEEL BEAM DESIGN METHOD
To provide a steel beam design method that can design a stiffening area with consideration of the effect of sear buckling in the case of stiffening only with use of a horizontal stiffener.SOLUTION: A steel beam design method of this invention comprises a computation step of a first stiffening length, a computation step of a second stiffening length, and a computation step of a stiffening length in which the length of the stiffening area 6 is set to be the same as or greater than the sum of the length of the first stiffening part 61 and the length of the second stiffening part 62. In the computation step of the first stiffening length, the design is made in such a way that, assuming there is not installed any horizontal stiffener 5 to the second stiffening part 62, but only installed to the first stiffening part 61, the yield strength Ma0 of the web 4 at a non-stiffening part 71 where no horizontal stiffener 5 is installed to is greater than the bending moment M2 caused on the web at the second end part 61b of the first stiffening part 61. In the computation step of the second stiffening length, the length of the second stiffening part 62 is set to be the same as the beam depth (1.0H) of the steel beam 1.SELECTED DRAWING: Figure 2
【課題】水平スチフナのみを用いて補剛を行う場合のせん断座屈の影響を考慮した補剛範囲を設計できる鉄骨梁の設計方法を提供する。【解決手段】第１スチフナ補剛長さ算出工程と、第２スチフナ補剛長さ算出工程と、スチフナ補剛部６の長さ寸法を第１スチフナ補剛部６１の長さ寸法と第２スチフナ補剛部６２の長さ寸法とを合わせた値以上とするスチフナ補剛長さ算出工程と、を有し、第１スチフナ補剛長さ算出工程では、水平スチフナ５が第２スチフナ補剛部６２には設けられず第１スチフナ補剛部６１のみに設けられていると想定し、第１スチフナ補剛部６１における第２端部６１ｂの位置に生じる曲げモーメントＭ２よりもウェブ４に水平スチフナ５が設けられていない無補剛部７１の耐力Ｍａ０が大きくなるように設計し、第２スチフナ補剛長さ算出工程では、第２スチフナ補剛部６２の長さ寸法を鉄骨梁１の梁せい寸法（１．０Ｈ）と同じ値に設定する。【選択図】図２
