| Abstract: | To study the wind vibration response of power transmission tower, the lead viscoelastic dampers (LVDs) were applied to a cup tower. With time history analysis method, the displacement, velocity, acceleration and force response of the tower was calculated and analyzed. The results show that the control effect of lead viscoelastic dampers is very good, and the damping ratio can reach 20% or more when they are applied to the tower head. |
