Negative Poisson's ratio two-way energy dissipation crossed type energy dissipation component
The invention discloses a negative Poisson's ratio two-way energy dissipation crossed type energy dissipation component which is characterized in that the negative Poisson's ratio two-way energy dissipation crossed type energy dissipation component comprises a frame (5) and a connecting piece (6), the frame (5) is a rectangular frame, the connecting piece (6) is arranged in the center of the frame (5), and core units (2) are movably connected between the connecting piece (6) and the four corners of the frame (5) respectively; negative Poisson's ratio holes are circularly arranged in the middle of the core unit (2), and the negative Poisson's ratio holes are at least two rows of positive and negative orthogonal semi-concave hexagonal holes. Under the action of an earthquake, the whole frame can laterally move, the lateral movement of the frame is transmitted to the four supports arranged along the two diagonals through axial force, the two supports on one diagonal are subjected to axial tension, and the two supports on the other diagonal are subjected to axial pressure. Concave hexagonal negative Poisson's ratio holes which are arranged in a circulating mode are formed in an energy consumption section of a core component in the support, and therefore the energy consumption section can deform.
本发明公开了一种负泊松比双向耗能的交叉型消能部件，其特征在于，包括框架(5)和连接件(6)，所述框架(5)为矩形框架，连接件(6)设置于框架(5)中心位置，连接件(6)与框架(5)的四个边角之间分别活动连接有核心单元(2)，核心单元(2)的中间部位设置有循环排列的负泊松比孔洞，负泊松比孔洞为至少两列正反正交的半内凹六边形孔洞。在地震作用下整个框架会发生侧向移动，框架的侧移通过轴向力传给沿两条对角线放置的四个支撑，则一条对角线上的两个支撑会受轴向拉力，另一条对角线上的两个支撑受轴向压力，支撑中核心构件的耗能段上设有循环排列的内凹六边形负泊松比孔洞，因而该耗能段会发生变形。
