TLD-结构体系转化为TMD-结构体系的减振计算方法
|
摘要
提出了调谐液体阻尼器(Tuned Liquid Damper,TLD)转化为调谐质量阻尼器(Tuned Mass Damper,TMD)对结构减振控制的计算方法,采用该方法可方便地采用能够容易数值模拟的TMD实现TLD对结构的减振控制分析。TLD-结构体系转化为TMD-结构体系的理论推导过程简洁、物理概念清晰,并通过实例分析了一幢250m的高层建筑结构,进而说明该文方法的可行性与合理性,可便于结构工程师直接利用商业有限元程序对TLD-结构体系进行数值仿真。
An equivalent calculation method for structural vibration control of a transforming TLD-structure to TMD-structure system is presented and proposed due to the easy implementation of TMD by numerical simulation.The derivation process of the transformation is reasonable and has explicit physical meaning.The analysis of a high-rise building structure 250m in height shows that the proposed method is feasible,accurate and can be directly used in the numerical analysis of the TLD-structure system by adopting commercial finite element software.
