PROBLEM TO BE SOLVED: To provide a damper brace used for a structure such as an iron bridge capable of observing deformation of a main member.SOLUTION: A structure of a damper brace is installed to an overpass, and absorbs axial directional force when shear panel members 56 and 57 are shear-deformed, and a first brace 21 and a second brace 22 are coaxially arranged in a brace shape on the overpass, and an end part 21A of the first brace 21 and an end part 22A of the second brace 22 are opposed and connected via a damper member 30, and the damper member 30 comprises the first shear panel members 56 and 57 projected in one end part of the first brace 21, the second shear panel members 56 and 57 projected in one end part of the second brace 22, and a connection member 31 for connecting outer end parts of the first and second shear panel members 56 and 57, and the shear panel members 56 and 57 comprise shear panel parts 56a and 57a being thin parts and flange parts 56b and 57b thicker than the shear panel parts 56a and 57a on its periphery.
【課題】主部材の変形を観察可能な鉄橋などの構造物に用いるダンパーブレースを提供する。【解決手段】高架橋に対して設置され、軸方向の力を剪断パネル部材５６、５７が剪断変形することによって吸収するダンパーブレースの構造において、第１ブレース２１と第２ブレース２２は同軸上に高架橋に筋交い状に配置され、第１ブレース２１の端部２１Ａと第２ブレース２２の端部２２Ａが向かい合い、ダンパー部３０を介して連結され、ダンパー部３０は、第１ブレース２１の一端部に突設された第１の剪断パネル部材５６、５７と、第２ブレース２２の一端部に突設された第２の剪断パネル部材５６、５７と、第１、第２の剪断パネル部材５６、５７の外方端部を連結する連結部材３１を有し、剪断パネル部材５６、５７は、薄肉部である剪断パネル部５６ａ、５７ａとその周囲に剪断パネル部５６ａ、５７ａより厚みのあるフランジ部５６ｂ、５７ｂを有する。【選択図】図４
