摘　　要：研究了基于调谐液柱阻尼器(TLCD)的建筑结构减震控制问题。建立了TLCD的力学模型,并得到了TLCD中液体的运动方程。在此基础上,建立了安装TLCD的结构的动力分析方法和减震控制方法。以经典20层Benchmark结构为例,研究了TLCD对多层建筑的减震效果。结果表明:TLCD结构简单、性能可靠,可以有效减小多层建筑的地震响应。Engineering structures may suffer severe damages and losses subjected to strong earthquakes.Thus,it be of important scientific value and actual engineering meanings to conduct the vibration control of engineering structures.The vibrant response control of multi-storey engineering structures by tuned liquid column dampers(TLCD)was actively investigated in this study.The principles of TLCD was firstly presented and then the mechanical model of TLCD was established to obtain the equation of motion of the liquid in TLCD was obtained.In addition,the dynamic analytical method and control approach of frame structures with TLCD were established.The control efficacy of TLCD was investigated by taking the classic 20-story benchmark structure as an example.The made observations indicate that TLCD has simple configuration as well as reliable performance and thus can be utilized to effectively suppress the seismic responses of multi-storey engineering structures.
