A steel beam with an H-shaped cross section. Its distinctive feature is its high resistance to compression and bending. It has a wider flange than an I-beam. Demand for it in construction is increasing due in part to simplified joints. Steel beams with a thicker flange than the web are called structural H-beams, and are used for building columns and beams. There are also steel beams with the same flange and web thickness called H-beams for foundation columns, which are used for foundation work on quays, buildings, bridges, etc. Source: Encyclopaedia Britannica Concise Encyclopedia About Encyclopaedia Britannica Concise Encyclopedia Information |
断面がH形をした形鋼。耐圧縮力や曲げに耐える力が大きい点が特色。I形鋼よりフランジの幅が大きくなったもの。継手が単純化されていることもあって建設用の需要がふえている。フランジの厚みがウェッブの厚みより大きいものを構造用H形鋼と呼び,ビルの柱や梁に利用する。またフランジとウェッブの厚みの等しいもので基礎柱用H形鋼といわれるものがあり,これは岸壁やビル,橋梁などの基礎工事に用いる。
