A viscous damper was invented in order to avoid some shortages of existing dampers and improve performance in a certain extent. Experiments on hysteretic and low-cycle fatigue property of the viscous dampers with four types( D1～ D4) were performed. Based on the experimental data,mechanical properties,such as energy dissipation performance,parameter related performance,were investigated in detail. And the new viscous damper was applied in a practical engineering. Results show that expected design requirements are well achieved for the new advanced viscous dampers.Good energy dissipation performance and low-cycle fatigue performance can be obtained according to experimental hysteretic curves. And the dampers have stable work performance and excellent tightness. The application study of the viscous damper shows that the viscous damper can dissipate energy imported by earthquake,attenuate inter-story displacement effectively. So,the viscous dampers are feasible and effective to control earthquake-induced vibration responses and then improve structural safety.
