Abstract:

通常采用数值模拟和小比例尺试验的方法研究调谐液体阻尼器(TLD)对结构的减振控制效果。由于TLD依靠水的晃动来提供减振力,精确的数值模型不易建立;另外,振动台模型试验又只能进行小比例尺试验,难以真实反映原型结构性能。为了解决这个问题,提出基于等效力控制方法的振动台子结构试验方法,以真实揭示TLD减振控制结构的抗震性能。通过试验研究得到如下结论(1)惯性试件的振动台子结构试验结果与精确解吻合很好,表明基于等效力控制方法振动台子结构试验具有很好的精度;(2)TLD减振控制三层钢框架系统的振动台全结构和子结构试验结果吻合较好,进一步证明了基于等效力控制方法振动台子结构试验具有很好的精度。
