Shape-optimized assembly type shear damper with staged yield energy dissipation mechanism
The invention discloses a shape-optimized assembly type shear damper with a staged yield energy dissipation mechanism. The damper comprises in-plane deformation energy dissipation sheets, out-of-planedeformation energy dissipation sheets, a first connecting plate and a second connecting plate; and the first connecting plate and the second connecting plate are arranged in parallel; the in-plane deformation energy dissipation sheets and the out-of-plane deformation energy dissipation sheets are fixedly arranged between the first connecting plate and the second connecting plate; a plurality of through holes are formed in each in-plane deformation energy dissipation sheet in the length direction in an array mode; each through hole is of a structure with the middle gradually collapsing towardsthe two ends; the two ends of each through hole face the first connecting plate and the second connecting plate respectively; two out-of-plane deformation energy dissipation sheets symmetrical relative to a corresponding in-plane deformation energy dissipation sheet are arranged in the middle of every two adjacent through holes; and a reserved seam is formed between the out-of-plane deformation energy dissipation sheets and the corresponding in-plane deformation energy dissipation sheet. The damper has the beneficial effects that the edge shapes of the in-plane deformation energy dissipationsheets and the out-of-plane deformation energy dissipation sheets of the damper are optimized, so that the stress distribution is more uniform, and the ductility is better.
本发明公开了形状优化的分阶段屈服耗能机制的装配式剪切型阻尼器，包括：面内变形耗能片、面外变形耗能片、第一连接板和第二连接板，第一连接板和第二连接板平行设置，面内变形耗能片和面外变形耗能片固定设置于第一连接板和第二连接板之间；其中，面内变形耗能片在长度方向上阵列式地开设有多个通孔，通孔为中间向两端逐渐收拢的结构，其两端分别朝向第一连接板和第二连接板，相邻两个通孔的中间部位设有两个关于面内变形耗能片对称的面外变形耗能片，且面外变形耗能片与面内变形耗能片之间存在预留缝。本发明的有益效果是通过对阻尼器面内变形耗能片和面外变形耗能片边缘形状进行优化，使得应力分布更加均匀，延性更好。
