MEMBER WITH BOX-SHAPED CROSS-SECTION, AND DESIGN METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a member with a box-shaped cross-section that combines a high-strength steel plate and a low-strength steel plate at appropriate plate thickness ratio and width-thickness ratio, thereby enhancing a degree of freedom of design, reducing an amount of welding, and saving labor for welding work management.SOLUTION: A member 1 with a box-shaped cross-section that applies the present invention has a plurality of steel plates welded and assembled to form a roughly rectangular cross-section, and includes a pair of high-strength steel plates 2 on a side surface and a pair of low-strength steel plates 3 on the other side surface, the side surfaces being opposite of each other. The low-strength steel plate 3 uses a steel material having yield strength smaller than the high-strength steel plate 2, and a plate thickness t1 of the low-strength steel plate 3 and a plate thickness th of the high-strength steel plate 2 are of relatively different values.SELECTED DRAWING: Figure 3
【課題】高強度鋼板と低強度鋼板とを適切な板厚や幅厚比で組み合わせることで、設計自由度を向上させて、溶接量の削減と溶接施工管理の省力化等を実現した箱型断面部材を提供する。【解決手段】本発明を適用した箱型断面部材１は、複数の鋼板を溶接して断面略矩形状に組み合わせたものであり、互いに対向する一方の側面で一対となった高強度鋼板２と、互いに対向する他方の側面で一対となった低強度鋼板３とを備える。低強度鋼板３は、高強度鋼板２よりも低い降伏強度とした鋼材が用いられて、低強度鋼板３の板厚ｔｌと高強度鋼板２の板厚ｔｈとが相対的に異なる大きさとなる。【選択図】図３
