As a new type of displacement-dependent ADAS (Added Damping And Stiffness) dampers, HADAS damper consists of several mild steel energy-dissipation plates, which can dissipate a large amount of seimic energy induced into the structure by their out-of-plane inelastic hysteresis cycles and effectively improve the seimic behavior of structure.

Simulation analysis on hysteretic behavior and vibration suppression of the mild steel damper with the diamond-shaped opening and added damping and stiffness;

Study on mechanical behavior and effectiveness of a new type of mild steel damper;

An experimental research on performance and application of a new type of mild steel damper added damping and stiffness(ADAS);

Earhquake-resistent design of reinforced concrete frame with metallic dampers of "dual functions";

A new idea of designing mild metallic damper is presented,it is that to strengthen the initial stiffness by extending the steel plate of the damper in its own plane and to increase the energy-dissipating ability by changing the geometric shape of the steel plate of the damper.

A three-dimensional five story frame structure model with and without metallic damper are made with ADPL language in ANSYS program.

Experimental study on seismic behavior of steel frameattached with hysteretic dampers;

Experimental and theoretical study on vibration control of steel frame attached with hysteretic dampers;

This paper studies the condition that structures should be in when hysteretic dampers mitigate seismic action most effectively in theory.
