摘要

为提高大跨悬挑结构的抗风性能，提出将圆柱螺旋弹簧与筒式黏滞阻尼器相结合设计形成弹簧-阻尼减振支座，并将其布置在柱顶与拉索配合起到竖向减振的作用。对该弹簧-阻尼减振支座的力学性能进行试验研究，依次开展了轴向刚度与低周往复加载试验共计61种工况，探究了静位移、位移幅值与加载频率对支座力学性能的影响，并基于有限元软件对安装弹簧-阻尼减振支座前后的体育场结构进行风振动力响应分析。结果表明，支座的轴向刚度随加载等级的增加而增大；支座的滞回耗能性能随位移幅值的增加而增大，等效阻尼比和等效刚度则随位移幅值的增大而减小；与支座性能随位移幅值的变化情况相比，其力学性能随加载频率的变化幅度更小，各个区段变化范围均小于±10%；静位移对支座的滞回耗能性能、等效刚度和等效阻尼比影响较小。弹簧-阻尼减振支座对大跨悬挑结构的风振响应具有显著的控制效果，最大达92.16%，平均38.79%。

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%.
