Bent metal damper
The bending type metal damper comprises an upper energy consumption plate fixedly connected with an upper connecting plate, a lower energy consumption plate fixedly connected with a lower connecting plate and a limiting device, and the limiting device is installed between the upper energy consumption plate and the lower energy consumption plate so as to limit in-plane deformation of the upper energy consumption plate and/or the lower energy consumption plate. The upper energy consumption plate and the lower energy consumption plate are connected through the limiting device instead of being directly connected, and the limiting device can provide limiting for in-plane deformation of the upper energy consumption plate and/or the lower energy consumption plate. The upper energy dissipation plate and the lower energy dissipation plate are two steel plates obtained by separating any one of X-shaped, double-X-shaped, diamond-shaped, triangular, rectangular or rectangular steel plates with holes in the middle from the median line, equivalently, the limiting device is located at the midpoint of the whole energy dissipation steel plate, the out-of-plane bending yield of the bent damper is achieved, the inflection point appears at the midpoint of the energy dissipation steel plate, and therefore the energy dissipation effect is achieved. And a limiting device is arranged at the midpoint, so that the adverse influence of a thin film effect generated during large deformation on the performance of the damper due to out-of-plane bending yield of the bent damper can be effectively overcome.
本发明公开一种弯曲型金属阻尼器，其包括与上连接板固定连接的上耗能板、与下连接板固定连接的下耗能板，以及限位装置，限位装置安装于上、下耗能板之间，以限制上耗能板和/或下耗能板的面内变形。上、下耗能板之间通过限位装置进行连接，而不是直接连接，限位装置能够提供上和/或下耗能板的面内变形的限位；上、下耗能板是X形、双X型、菱形、三角形、矩形或中间开孔矩形钢板中任意一种自中位线处分开得到的两块钢板，相当于限位装置位于整块耗能钢板的中点处，弯曲型阻尼器的面外受弯屈服，反弯点出现在耗能钢板的中点处，在中点处设置限位装置，能够有效克服弯曲型阻尼器面外受弯屈服，在大变形时产生的薄膜效应对阻尼器性能不利的影响。
