| Abstract: | In this paper,two types of arc-shaped steel dampers have been researched.Based on the steel's dissipating energy in hysteresis of plastics,the design formula of the arc-shaped steel dampers and damping force hysteresis loop model are derived.To verify the mechanical characteristics of two types of arc-shaped steel dampers,the FEA simulations and product tests have been done,and the comparative analysis of the results obtained in two ways is made.The results show that the arc-shaped steel dampers have higher... |
