In order to make up for the lack of single form of energy dissipation of the existing mild steel dampers, a new type of staged yield mild steel damper is proposed by combining two different forms of energy dissipation steel plates. Its construction and energy dissipation mechanism are introduction, based on the relevant theory, the expression of mechanical properties parameters are derived, and the finite element software ABAQUS is used to simulate the staged yield mild steel damper with different parameters. The results show that the staged yield mild steel damper not only possesses full hysteretic loops and excellent energy dissipation capacity, but also achieves staged yield function effectively. The height of the staged yield mild steel damper is an important factor affecting its yield displacement and hysteretic performance.
