The damping model parameters are identified by nonlinear dynamic test for Viscous Damping(VD) wall. Rotating motion can cause some changes for the shearing model of the VD wall. The changest of nonlinear damping property is studied with varing vibration frequency and amplitude. The formula of the viscous damping model is produced for engineering application. The result shows that the VD wall has a good damping property for tall building in shearing ldeformation. It is shown that the rotation motion has obvious affect on the damping property of the VD wall. The conclusions can be applieol to dynamic design for earthquake and wind induced vibration control of tall buildings.
