Four-stage grading yield damper and using method thereof
The four-stage graded yield damper comprises a lower base plate and an upper base plate which are distributed at intervals, a first yield energy dissipation piece is installed between the lower base plate and the upper base plate, and a second yield energy dissipation piece, a third yield energy dissipation piece and a fourth yield energy dissipation piece are installed between the lower base plate and a baffle; the first yield energy dissipation piece comprises at least two first energy dissipation metal plates arranged in parallel, the upper ends and the lower ends of the first energy dissipation metal plates are fixedly connected with the lower base plate and the upper base plate correspondingly, and the second yield energy dissipation piece comprises at least two second energy dissipation metal plates arranged in parallel and symmetrically arranged on the inner sides of the first energy dissipation metal plates on the left side and the right side. The third yield energy dissipation piece comprises at least two third energy dissipation metal plates which are arranged in parallel and symmetrically arranged on the inner side of the second energy dissipation metal plate, the fourth yield energy dissipation piece is symmetrically arranged on the inner side of the third energy dissipation metal plate, and the upper ends of the second yield energy dissipation piece, the third yield energy dissipation piece and the fourth yield energy dissipation piece stretch into sawtooth grooves of the baffle correspondingly. And gaps are formed between the inner walls of the sawtooth grooves.
