摘　　要：该文针对平面对称结构和不对称结构,比较TLCD-结构体系和TMD-结构体系的耦联微分方程,得到TLCD-主结构与TMD-主结构质量比、频率比、主结构自振频率和主结构阻尼等,由此可将TLCD-结构体系转化为TMD-结构体系,利用Den Hartog公式对TLCD阻尼比和频率比参数优化,并用有限元软件来对复杂结构减振控制进行数值计算。通过单层平面不对称结构和20层Bechmark模型放置单个或多个TLCD,用Den Hartog公式求得TLCD参数,并用SAP2000进行结构分析,与MATLAB结果进行比较来验证该方法的合理性和可行性。Comparing the coupled differential equations of a TLCD （tuned liquid column damper）-structure and a TMD （tuned mass damper）-structural system for plan-symmetric and plan-asymmetric buildings, the mass ratio, the optimal frequency ratio, the natural frequency, and the damping of a main structure are achieved. The transformation of a TLCD-structure to a TMD-structure system is investigated. The modal tuning of the TLCD （frequency ratio and damping） is classically performed by applying the Den Hartog optimization criterion. The analysis of structural vibration control using finite element software is presented. A single-storey plan-asymmetric structure and a 20-storey benchmark model with a single TLCD or TLCDs are numerical simulated; the TLCD parameters using Den Hartog formula are obtained; and the structural analysis by SAP 2000 software is performed and compared with the results obtained from MATLAB. It is shown that the method for transforming a TLCD-structure to a TMD-structure system is reasonable and feasible.
