BOX-SHAPED CROSS SECTION MEMBER AND IS DESIGN METHOD
To provide a box-shaped cross section member which can be rationally structured by effectively using bearing forces possessed by steel plates constituting the box-shaped cross section member, and its design method.SOLUTION: In a welding/assembling box-shaped cross section member which is formed by welding a plurality of steel plates in a state that the steel plates are combined so as to exhibit rectangular cross sections, plate thicknesses t1, plate widths D1 and yield strength σy1 of first plates which are arranged at a pair of opposing faces out of the plurality of steel plates, and plate thicknesses t2, plate widths D2 and yield strength σy2 of second plates which are arranged at the other pair of opposing faces are set so as to satisfy relationships of t1>t2 and σy1<σy2, and maximum bending bearing forces Myh1 when receiving bending in a direction in which the first plates form webs, and maximum bending bearing forces Myh2 when receiving bending in a direction in which the second plates form webs are set so as to satisfy a prescribed equation.SELECTED DRAWING: Figure 1
【課題】箱形断面部材を構成する各鋼板が有する耐力を有効に活用して、合理的な構造とすることのできる、箱形断面部材およびその設計方法を提供する。【解決手段】複数の鋼板を、矩形状断面となるように組み合わせた状態で溶接して形成される箱形断面部材において、前記複数の鋼板のうち、向かい合う一対の面に配置される第一の鋼板の板厚ｔ１、板幅Ｄ１および降伏強度σｙ１、ならびに、向かい合う他の一対の面に配置される第二の鋼板の板厚ｔ２、板幅Ｄ２および降伏強度σｙ２が、ｔ１＞ｔ２およびσｙ１＜σｙ２の関係を満たすとともに、前記第一の鋼板がウェブとなる方向に曲げを受けるときの最大曲げ耐力Ｍｙｈ１、前記第二の鋼板がウェブとなる方向に曲げを受けるときの最大曲げ耐力Ｍｙｈ２が、所定の式の関係を満たすようにする。【選択図】図１
