This paper supposes a U-shape low yield steel damper.Based on the mechanical behaviors of the damper,its analytical model is established.Meanwhile,the damper＇s hysteretic characteristics are numerically simulated by the FEM ANSYS to obtain the main mechanical parameters of this damper.These parameters are compared with the results from the established analytical model.Results indicate that the analytical model is agreeable to the FEM analysis.In addition,Analytical results also show that the U-shape low yield damper possesses superior mechanical behaviors and hysteretic characteristics to fit extremely for mitigating the vibration of engineering structures.
