摘　　要：本文通过钢结构的振动台模型试验,研究了在刚性地基条件下矩形调谐流体阻尼器(TLD)对结构地震反应的减震机理和减震效果,为进一步研究土-结构相互作用对结构TLD减震控制效率影响的振动台模型试验提供对比数据。试验结果表明,在水箱中设置铁丝网有助于提高TLD的减震效率,地震动的频谱特性和峰值加速度大小对TLD的减震效率有重要影响。The results of a series of shaking table tests of a steel structural model setting on rigid foundation are introduced. The purpose of these tests is to study the mechanism and efficiency of the tuned liquid damper for suppressing the seismic responses of the structure. The numerical results will be taken as the comparison data for studying the effect of soil - structure interaction on the control efficiency of the tuned liquid damper in reducing the seismic responses of the structure. The test results show that the capacity of TLD for suppressing the seismic responses of the structure can be enhanced when the grille fence is set in TLD device. The amplitudes of the seismic motion acceleration as well as the frequency spectrum features of the input have important effects on the control behavior of TLD.
