摘要
本文以洛阳某高层建筑为工程背景,探讨了安装非线性粘滞流体阻尼器对其顶部钢塔风振响应的振动控制。按照随机振动理论,仿真得到了作用在结构上的人造脉动风压时程样本曲线,并利用时程样本进行了安置了粘滞流体阻尼器的结构的风振控制分析;对粘滞流体阻尼器进行了相关检测。研究结果表明,工程用粘滞流体阻尼器性能稳定,可以有效降低结构的风振响应。
In this paper,a Luoyang high-rise building is used as an analytical case to examine the wind control of the stell tower with Fluid Viscous Damper.According to the random vibration theory,the effect of fluctating wind on the structure can be modeled as correlated random process,and the wind vibration control analysis of the structure using fluid viscous damper were stuided.The fluid viscous dampers were tested.Analysis results show that the performance of the Fluid Viscous Damper which used the structure are steady and the wind-induced response of the structure can be reduced effective.
