ABSTRACT:

This paper summarizes the research results in mild steel dampers at home and abroad in recent years. In view of disvantages such as out-of-plane deformation, a new stiffened perforated mild steel damper is proposed. The geometric parameters of the damper is designed by numerical analysis of sensitivity of out -of-plane buckling. This opotimizing method can reduce the computation time. Unidirection damping performance tests are conducted in five different loading system. Tests results show that this kind of dampers have good energy dissipation capacity, but the low sycle fatigue properties of them should be improved in material and processing quality. And for incomplete plastic deformation while unloading, a non-symmetrical design should be taken into consideration.
