STEEL FRAMEWORK SKELETON STRUCTURE AND DESIGN METHOD THEREOF
To provide a steel framework skeleton structure for realizing a large space structure at a lower layer, with little change of a standardized design rule and members of an upper layer part, and a design method thereof.SOLUTION: A steel framework skeleton structure 100 related to the present invention has an upper layer of a first steel rigid-frame 101 in a one direction rigid frame and a second steel rigid-frame 102 in two directions rigid frame constituted by a steel pipe column 11 of a rectangular section and an H-shape steel beam 14 arranged thereunder. The H-shape steel beam 14 constituting the second steel rigid-frame 102 has a flange width twice or more of the width of the upper layer first steel rigid-frame 101. A beam facing an outer wall 8 out of the H-shape steel beam 14 of the second steel rigid-frame 102 is fixed to the steel pipe column 11 with an end face of the outer wall 8 side of a beam flange 17 almost aligned with an extended line of a face of the outer wall 8 side of the steel pipe column 11, and is arranged with a beam center of the first steel rigid-frame 101 aligned at a position of 1/2 of the beam flange width of an H-shape steel beam 4 of the first steel rigid-frame 101 from the outdoor side of the flange.SELECTED DRAWING: Figure 1
【課題】規格化された上層部の設計ルールや部材を殆ど変更することなく、下層に大空間構築を実現できる鉄骨骨組み構造、鉄骨骨組み構造の設計方法を提供する。【解決手段】本発明に係る鉄骨骨組み構造１００は、１方向ラーメンによる第一の鉄骨ラーメン架構１０１を上層とし、その下層に、矩形断面の鋼管柱１１とＨ形鋼梁１４で構成した２方向ラーメンによる第二の鉄骨ラーメン架構１０２を配置するものであって、第二の鉄骨ラーメン架構１０２を構成するＨ形鋼梁１４は、フランジ幅が上層の第一の鉄骨ラーメン架構１０１の梁フランジ幅の２倍以上であって、第二の鉄骨ラーメン架構１０２のＨ形鋼梁１４のうち外壁８に面する梁は、鋼管柱１１の外壁８側の面の延長線上に梁フランジ１７の外壁８側の端面を略一致させて鋼管柱１１に固定されており、かつ、そのフランジの屋外側から前記第一の鉄骨ラーメン架構１０１のＨ形鋼梁４の梁フランジ幅の１／２の位置に、第一の鉄骨ラーメン架構１０１の梁芯を一致させて配置した。【選択図】 図１
