Abstract

In order to improve the wind-resistant performance of large cantilever structure, spring-damping anti-vibration bearings which combine cylindrical helical springs with cylinder-type viscous damper are arranged on the top of the column to cooperate with the cable to reduce the vertical vibration. The mechanical properties of the spring-damping bearing were tested to study the effects of static displacement, displacement amplitude and loading frequency on the mechanical properties of bearings，and the axial stiffness and low-frequency cyclic loading tests were carried out successively for a total of 61 conditions, and analyzed the wind-induced vibration response and the performance of vibration reduction with the analysis software. The results shows that the axial stiffness of the bearing increases with the increase of the loading level. The energy dissipation capacity of the bearing increases, the equivalent stiffness an effective damping ratio loss with the increase of displacement amplitude. Compared with the changes of the mechanical properties in different displacement amplitudes, they had a smaller variation with loading frequency, and the variation range of each segment was less than ±10%. The static displacement has a slight impact on these mechanical properties. The effect of adding spring-damping anti-vibration bearings was obvious for controlling the wind-induced vibration response, and the maximum reduction reaches 92.16%, average 38.79%.
