- 構造物に取り付けられて、振動エネルギーを吸収する制震ダンパであって、
板状の本体には、断面形状が略矩形の柱部が形成され、
前記柱部の外形は、前記柱部の中央と基部との間の所定の範囲に、前記柱部の中央方向に凸となる二次曲線からなる曲線部と、前記曲線部と前記柱部の基部とをつなぐ柱端部とからなり、
前記曲線部と前記柱端部とがなだらかに接続され、
前記柱端部は、前記柱部の基部に設けられた円弧部と、前記曲線部と前記円弧部とをつなぐ直線部と、を具備し、
前記柱端部が、前記曲線部の二次曲線の延長線よりも外側に形成され、前記柱端部の部位で、前記曲線部の二次曲線の延長線の幅よりも前記柱部の幅が大きく、
前記本体の面内方向における前記柱部の危険断面位置と、
前記面内方向に垂直な方向の面外方向における前記柱部の危険断面位置と、が異なり、
前記面外方向の危険断面位置は、前記柱部の基部であり、
前記面内方向の危険断面位置は、前記柱部の基部から、前記柱部の中央部側にずれた前記曲線部と前記柱端部との接続位置となることを特徴とする制震ダンパ。 - 前記柱部の高さHに対して、前記面内方向の危険断面位置は、前記柱部の基部から、H/20以上離れた位置であることを特徴とする請求項1記載の制震ダンパ。
- 前記柱部の高さHに対して、前記面内方向の危険断面位置は、前記柱部の基部から、H/10以上離れた位置であることを特徴とする請求項1または請求項2に記載の制震ダンパ。
