Background technique
Metallic damper (metallic yielding damper) is made of mild steel or other softer metals
At various forms of damping energy dissipation devices.There is good Hysteresis Behavior after metal yield, moulded using the bullet that certain metals have
Property hysteresis deformation energy consumption, including mild steel damper, lead damper and marmem (shape memory alloys, letter
Claim SMA) damper etc..The mechanism that it carries out vibration control to structure is the surrender that the portion of energy of structural vibration is passed through metal
Hysteretic energy dissipates, to achieve the purpose that reduce structural response, mild steel damper is that mild steel is made full use of to enter plasticity rank
There is good hysteretic characteristic after section.1972, the American scholars such as Kelly and Skinner were first begin to research and utilization mild steel
This performance carry out the dynamic response of control structure, and propose several forms of mild steel damper, including torsion beam, bent beam, U
Shape energy consumer etc..Then, other scholars again propose the different mild steel damper of many forms in succession, wherein than it is more typical such as
X shape, triangular plate mild steel damper, E shape steel damper, C-type steel damper etc..By the theory point of many scholars at home and abroad
Analysis and experimental study, it was demonstrated that mild steel damper has stable hysteretic characteristic, good low cycle fatigue property, long-term reliability
The features such as not influenced by environment, temperature, be a kind of up-and-coming energy consumer, and all metal damper has recoverable deformation
