Tuned liquid dampers provide structure control with the help of the liquid mass in tanks that are attached to the structure. The mass ratio affects the optimum tuned liquid damper (TLD) parameters. This study examines the effect of mass ratio on the control performance of TLD devices in providing seismic control of structures with different damping ratios. For this purpose, TLD devices with different mass ratios were placed on two different single-story steel and reinforced concrete structure models, and their performance under earthquake excitation was investigated. TLD parameters for obtaining the optimum displacement level in the 0.5- and 1.0-s structure natural period for both structure types were optimized with the Jaya algorithm (JA), which is a metaheuristic algorithm. By using the optimum TLD parameters, the structural displacement and total acceleration values were obtained by the critical earthquake analysis. When the results are examined, it is understood that TLD mass increase from a 20% mass ratio for both structure types and selected structure periods does not have a significant effect on TLD control performance.

最佳调谐液体阻尼器控制性能的质量比因子

调谐液体阻尼器借助连接到结构的储罐中的液体质量来提供结构控制。质量比影响最佳调谐液体阻尼器 (TLD) 参数。本研究探讨了质量比对 TLD 装置控制性能的影响，以提供不同阻尼比的结构的地震控制。为此，将不同质量比的TLD装置放置在两种不同的单层钢结构和钢筋混凝土结构模型上，并研究其在地震激​​励下的性能。使用 Jaya 算法 (JA)（一种元启发式算法）对两种结构类型在 0.5 秒和 1.0 秒结构自然周期内获得最佳位移水平的 TLD 参数进行了优化。利用最佳TLD参数，通过临界地震分析获得了结构位移和总加速度值。检查结果后发现，对于两种结构类型和选定的结构周期，TLD 质量从 20% 质量比增加不会对 TLD 控制性能产生显着影响。
