Bidirectional shear damper and fatigue judgment method of bidirectional shear damper
The bidirectional shear damper comprises a connecting assembly, a first energy dissipation assembly, a second energy dissipation assembly and a third energy dissipation assembly, the connecting assembly comprises a first connecting piece and a second connecting piece, and the two ends of the first energy dissipation assembly are connected with the first connecting piece and the second connecting piece correspondingly; the second energy dissipation assembly comprises a first energy dissipation piece and a second energy dissipation piece which are oppositely arranged in the first direction, the first energy dissipation assembly is located between the first energy dissipation piece and the second energy dissipation piece, and the third energy dissipation assembly comprises a third energy dissipation piece and a fourth energy dissipation piece which are oppositely arranged in the second direction. The first energy dissipation assembly is located between the third energy dissipation piece and the fourth energy dissipation piece, and the first direction and the second direction are arranged in a staggered mode so that shearing force borne by the first energy dissipation assembly can be reduced, deformation of the first energy dissipation assembly can be relieved, and therefore the fatigue life of the bidirectional shear damper can be prolonged. In addition, a fatigue prediction method of the bidirectional shear damper is also provided, and the fatigue life of the bidirectional shear damper can be accurately predicted.
本发明公开了一种双向剪切阻尼器，包括连接组件、第一耗能组件、第二耗能组件及第三耗能组件，连接组件包括第一连接件和第二连接件，第一耗能组件的两端分别与第一连接件和第二连接件连接，第二耗能组件包括沿第一方向相对设置的第一耗能件和第二耗能件，第一耗能组件位于第一耗能件和第二耗能件之间，第三耗能组件包括沿第二方向相对设置的第三耗能件和第四耗能件，第一耗能组件位于第三耗能件和第四耗能件之间，第一方向与第二方向交错设置，以减少第一耗能组件所受到的剪力，能够减缓第一耗能组件的变形，从而提高双向剪切阻尼器的疲劳寿命。此外，一种双向剪切阻尼器的疲劳预测方法也被提出，能够准确的预测双向剪切阻尼器的疲劳寿命。
