DAMPER BODY AND MANUFACTURING METHOD OF DAMPER BODY
PROBLEM TO BE SOLVED: To provide an inexpensive damper body having high energy absorptive capacity.SOLUTION: A damper body constitutes a framework of a structure; is used to control vibration of a junction structure comprising two parallel columns and a lateral member parallel with a vertical direction of the columns; and has an elastic deformation part comprising a square steel pipe. The square steel pipe has both opposite side surfaces as shear force application surface to which shear force in a direction vertical to an axial direction of the square steel pipe is applied, and surfaces orthogonal to the shear force application surface, as an elastic deformation surface whose cross sectional area gradually expand from a center part toward the shear force application surface.SELECTED DRAWING: Figure 1
【課題】安価でエネルギー吸収能力の高いダンパー体を提供すること。【解決手段】構造物の骨組を構成する、平行する２本の柱と、その上下に平行する横架材と、からなる接合構造の制振に用いるダンパー体であって、角形鋼管からなる弾塑性変形部を有し、前記角型鋼管は、対向する両側面を前記角形鋼管の軸方向に垂直な方向のせん断力がかかるせん断力作用面とし、前記せん断力作用面と直交する面はそれぞれ、中央部から前記せん断力作用面にむけて漸次断面積が広くなる弾塑性変形面とすることを特徴とする、ダンパー体。【選択図】図１
