【Abstract】 A new type of viscous damper was developed to avoid some disadvantages of existing dampers and improve their performance.Experiments on hysteretic and low-cycle fatigue performance for six viscous dampers with different types(D1~D6) were conducted and the mechanical properties of the damper in respect of energy dissipation performance,parameter related performance and restoring force model were investigated.The results indicate that the expected design requirements are well achieved by the new viscous dampers.Good energy dissipation performance and low-cycle fatigue performance can be obtained thorugh the analysis of experimental hysteresis curves,and the dampers show stable working performance and excellent air-tightness.The restoring force model of the new viscous dampers can be described by the Maxwell model very well and good agreement on the hysteresis curves between experiment and theory can be obtained.更多还原
