چکیده انگلیسی
In this study, the performance of tuned liquid column dampers (TLCDs) for controlling wind induced responses of a 76-story benchmark building is evaluated. The optimal design parameters such as headloss coefficient, tuning ratio, and mass ratio are numerically obtained by using the white noise and harmonic load in addition to the deterministic wind loads given by the benchmark problem as wind data. Further, the robustness of multiple TLCDs is investigated, and the effects of mass ratio, the number of dampers, central tuning frequency ratio, and the frequency range on the performance of multiple TLCDs are evaluated. Finally, the effectiveness of equivalent linear system for the benchmark building with nonlinear TLCDs is investigated. The equivalent linear system is obtained first in terms of an equivalent linear damping and second in terms of an equivalent single degree of freedom system.
