COLUMN BEAM STRUCTURE HAVING VIBRATION DAMPING STRUCTURE
PROBLEM TO BE SOLVED: To provide a column beam structure having a vibration damping structure, which has no disadvantage in cost when being compared to a conventional aseismic structure, which has less restriction in requirements for design and site when being compared to a conventional damping structure or seismic isolation structure, and which may absorb big energy from small deformation level so as to efficiently exert vibration damping effect.SOLUTION: In the column beam structure having a vibration damping structure, a plastic hinge part 15 is arranged on a beam end part and/or a column end part of a building, a vibration damping structure is realized by constructing the beam end part and/or the column end part in a manner where rigidity and/or yield resistance of the plastic hinge part is smaller than that of a member other than the plastic hinge part, and the plastic hinge part is configured in a manner where yield of the plastic hinge part starts from at least 1/150 in deformation angle of the building.SELECTED DRAWING: Figure 1
【課題】従来の耐震構造と比べコスト的に遜色がなく、従来の制振構造や免震構造と比べても意匠・敷地的な条件に制約されず、また、小さな変形レベルから大きなエネルギーを吸収し効率的に減振効果を発揮可能な減振構造を有する柱梁構造を提供する。【解決手段】この減振構造を有する柱梁構造は、建物の梁端部および／または柱端部に塑性ヒンジ部１５を設け、塑性ヒンジ部における剛性および／または降伏耐力が塑性ヒンジ部以外の剛性および／または降伏耐力と比べて小さくなるように梁端部および／または柱端部を構成することで減振構造を設け、塑性ヒンジ部は、塑性ヒンジ部における降伏が建物の変形角が少なくとも1/150で始まるように構成される。【選択図】図１
