Gantry type mild steel energy dissipation device with negative Poisson's ratio shearing steel plate
The portal type mild steel energy dissipater is characterized in that the portal type mild steel energy dissipater comprises a frame and a shear steel plate energy dissipater body, the frame is rectangular, an upper transverse steel plate of the shear steel plate energy dissipater body is fixedly connected with the inner side of one side of the frame, and inclined supports are fixedly connected between a lower transverse steel plate and the two corners of the opposite sides of the frame; the middle steel plate is provided with linearly arranged negative Poisson's ratio holes, and the negative Poisson's ratio holes are crossed arrow-shaped holes, or concave hexagonal holes or semi-concave hexagonal holes. The whole frame can laterally move under the action of an earthquake, the negative Poisson's ratio shear steel plate energy dissipater laterally moves along with the negative Poisson's ratio shear steel plate energy dissipater, and the mild steel plate is changed into a parallelogram from a rectangle due to shear force and is lengthened in the diagonal direction; the negative Poisson's ratio shear steel plate energy dissipater dissipates energy through deformation of the negative Poisson's ratio arrow-shaped holes arranged along the diagonal lines, when the holes are pressed and deformed to the limit, the energy is further borne and dissipated by deformation of the steel plate, and therefore the two-stage energy dissipation process is generated.
本发明公开了一种具有负泊松比剪切钢板的门架型软钢消能器，其特征在于，包括框架和剪切钢板消能器，框架为矩形，剪切钢板消能器的上横钢板与框架一边内侧固定连接，下横钢板与框架对边两角间固定连接有斜向支撑，中间钢板上设置有线性排列的负泊松比孔洞，负泊松比孔洞为交箭头型孔洞，或内凹六边形孔洞，或半内凹六边形孔洞。能够在地震作用下整个框架会发生侧向移动，负泊松比剪切钢板消能器随着发生侧向移动，软钢板受剪切力由矩形变为平行四边形，其沿对角线方向变长，负泊松比剪切钢板消能器通过所打沿对角线排列的负泊松比箭头型孔洞的变形而耗能，当孔洞受压变形到极限时，能量进一步由钢板的变形承担耗散，从而产生两阶段的耗能过程。
