In this project, analytical and experimental studies to establish design methodology of tuned liquid damper were performed. Firstly, the method for calculating the effectiveness of shallow water type rectangular tuned liquid damper(TLD) when installed on the actual buildings or bridges was established and the validity of which was verified by experiments. Especially, the effect of the inserted submerged nets on the performance of TLD was examined intensively. Secondly, deep water type TLD in which shallow water theory is no more applicable, was formulated based on the finite amplitude wave theory. The method for estimating the effectiveness of deep water type TLD when installed on the actual buildings or bridges was also established and the validity of which was verified by experiments. Thirdly, the fact that TLD is effective both with a small initial amplitude (which is less than about 5cm) such as the case of wind loadings and with a large initial amplitude such as the case of earthquake was first found experimentally. To establish suitable model for calculating the performance of TLD with a large initial amplitude is our future research topics.

本计画针对调谐液体阻尼器的设计方法进行分析与实验研究。首先，建立了安装在实际建筑物或桥梁上的浅水型矩形调谐液体阻尼器（简称矩形调谐液体阻尼器）的有效性计算方法，并通过试验验证了该方法的有效性。特别是，深入研究了插入式沉网对沉管性能的影响。其次，基于有限振幅波理论，建立了浅水波理论不再适用的深水型波浪模型。建立了在实际建筑物或桥梁上安装深水型减阻剂的减阻效果评价方法，并通过试验验证了该方法的有效性。第三，首次在实验上发现，在风荷载等小初始振幅（小于5cm）和地震等大初始振幅情况下，阻尼器都是有效的。建立合适的模型来计算具有较大初始振幅的双稳态振荡器的性能是我们未来的研究方向。
