Description
この発明の目的は、低サイクル疲労耐久性を向上させることができる鋼製ベローズ型ダンパーを提供することにある。
すなわち、この発明は、2つの構造物間を連結して、これら2つの構造物間に生じる相対変位を抑制するための鋼製ベローズ型ダンパーであって、
湾曲板部と、この湾曲板部の両端から互いに略平行となるように延びる1対の平板部とを有し、前記構造物に作用する外力により前記平板部が互いに接近及び離間するように弾塑性変形する本体と、
前記各平板部の外面に添接される添接部と、この添接部に略直角に設けられ前記構造物に取り付けられる取付部とを有する断面L字形のブラケットとからなることを特徴とする鋼製ベローズ型ダンパーにある。
