COLUMN-BEAM CONNECTION STRUCTURE
To provide a column-beam connection structure with a one-sided horizontal haunch beam having sufficient deformation performance while preventing beam end fracture.SOLUTION: The column-beam connection structure includes: a column; a beam that has a reference flange to be connected to the column and a one-side widened part of the reference flange toward the column. Defining a position where the widening of the one side starts as the haunch tip position, the dimension from the haunch tip position to the end of the beam where the beam is connected to the column as haunch length Lh, the width dimension of the reference flange as flange width Bf, and the width dimension of the one-side widening part as haunch width Bh, the haunch tip position reaches full plastic moment before or at the same time as the beam end position. In the column-beam connection structure, a specific ratio α that is obtained from the total plastic moment of the beam end joint endMf and the fully plastic moment endMf,d required for the beam end joint calculated by a specific formula meets the specified conditions.SELECTED DRAWING: Figure 1
【課題】片側水平ハンチ梁において、梁端の破断を抑制し、十分な変形性能を有する。【解決手段】柱と、前記柱に接続される基準フランジ部と、前記柱に向かって前記基準フランジ部の一方側を拡幅した一方側拡幅部と、を有する梁と、を有し、前記一方側拡幅部の拡幅が開始される位置をハンチ先端位置とし、前記ハンチ先端位置から前記梁が前記柱と接続する梁端の梁端位置までの寸法をハンチ長さLhとし、前記基準フランジ部の幅寸法をフランジ幅Bfとし、前記一方側拡幅部の拡幅寸法をハンチ幅Bhとした場合に、前記梁端位置よりも先に、又は前記梁端位置と同時に、前記ハンチ先端位置が全塑性モーメントに到達する柱梁接続構造であって、特定の式で求められる、前記梁端の仕口部の全塑性モーメントendMfと、前記梁端の仕口部に要求される全塑性モーメントendMf,dとにより、求められる特定の比率αが所定の条件を満たす柱梁接続構造である。【選択図】図１
