H-SHAPE STEEL MEMBER
PROBLEM TO BE SOLVED: To provide an inexpensive H-shape steel member that has been developed for solving a problem involved in a conventional H-shape steel member, and that has proper strength and can be reasonably used, and that is used for; a beam supporting a floor of a structure and a floor slab of a roof; and a girder designed within an elastic range of a steel material.SOLUTION: The H-shape steel member related to the present invention is a steel structure member which has a biaxially symmetrical H-shaped cross section having upper-lower flanges and a web, and which is used under the condition that both ends of the member are considered to be pin-supported and an equal distribution load acts on the member. In the H-shape steel member, a ratio L/H of L to H satisfies the following condition (I), and design basis strength F(N/mm) satisfies the following condition (II) when a thickness of the steel material constituting the member is 40 mm or less, tensile strength of the steel material is 300-510 N/mm, H denotes a height of the H-shape steel, L denotes a span (distance between supporting points) of the member and a defection limitation of the member is 1/k of the span L. L/H>6281/k : (I) 195≤F<235 and F≥1,476,000/{k×(L/H)} : (II).
【課題】本発明はかかる課題を解決するためになされたものであり、構造物の床や屋根などの床版を支持する小梁や、鋼材の弾性範囲内で設計する梁に用いられるH形鋼部材であって、安価で適切な強度を有し、合理的な持ち方のできるH形鋼部材を提供する。【解決手段】本発明に係るH形鋼部材は、上下フランジとウェブを有する二軸対称のＨ形断面を有し、部材両端がピン支持とみなされる接合条件で、かつ、等分布荷重が作用する鋼構造部材であって、部材を構成する鋼材の厚さが40mm以下、鋼材の引張強さが300〜510N/mm2で、H形鋼の高さをH、部材のスパン（支点間距離）をL、部材のたわみ制限をスパンLの1/kとしたとき、LとHの比L/Hが下記の条件(I)を満たすとともに、設計基準強度F(N/mm2)が下記の条件(II)を満たすことを特徴とするものである。L/H＞6281／k ：(I)195≰F＜235 かつ F≧1,476,000／｛k?(L/H）｝ ：(II)【選択図】 図１
