It is urgent to design a damper with low yield point, durability, excellent energy consumption performance and convenient large-scale use. And analyzing the stress-strain condition of the frame structure under the shearing force by a bionic principle. After a frame structure formed by four point positions in a plane is subjected to shearing force, because no support is arranged in the middle, the energy of the frame structure is transferred to the bending and shearing deformation of a frame beam and the buckling deformation at the node, the other extreme condition opposite to the bending and shearing deformation is the shear wall, and the middle part of the shear wall forms enough rigidity so that the shearing resistance is greatly improved.
