NON-DIAPHRAGM TYPE COLUMN BEAM JOINT STRUCTURE
PROBLEM TO BE SOLVED: To provide a non-diaphragm type column beam joint structure with excellent plastic deformation capability and safety by preventing a welded part of a column from fracturing first when external force is applied.SOLUTION: In a non-diaphragm type column beam joint structure, a column and a steel pipe for a joint are joined at a column welding part, the steel pipe for the joint has a thicker part thicker than a thickness of the column plate and a thinner part thinner than the thickness of the thicker part, and the thinner part and the column welding part satisfy the following formula (1): pZp×pσy≤cZp×wσy...(1), where pZp: plastic section modulus of the steel pipe for the joint at the thinner part(mm), pσy: yield strength of material forming the steel pipe for the joint(N/mm), cZp: plastic section modulus of the column(mm), and wσy: yield strength of welding material(N/mm).SELECTED DRAWING: Figure 1
【課題】外部から力を加えられた際に、柱溶接部における破断が先行することを回避し、塑性変形能力及び安全性に優れたノンダイアフラム型の柱梁接合構造体を提供すること。【解決手段】柱と仕口用鋼管とは柱溶接部により接合され、前記仕口用鋼管は、前記柱の板厚以上となる板厚を備えた増厚部と、前記増厚部よりも小さい板厚を備えた減厚部と、を有し、前記減厚部と前記柱溶接部とは、以下の式（１）を満たすノンダイアフラム型の柱梁接合構造体。ｐＺｐ×ｐσｙ≦ｃＺｐ×ｗσｙ ・・・（１）ｐＺｐ：前記減厚部における仕口用鋼管の塑性断面係数（ｍｍ３）ｐσｙ：仕口用鋼管を形成する材料の降伏耐力（Ｎ／ｍｍ２）ｃＺｐ：前記柱の塑性断面係数（ｍｍ３）ｗσｙ：溶接材料の降伏耐力（Ｎ／ｍｍ２）【選択図】図１
