چکیده:

This paper investigates the optimized parameters for the tuned liquid column dampers (TLCDs) to decrease the earthquake vibrations of high-rise buildings. Considering soil effects, the soil-structure interaction (SSI) is involved in this model. The Since the TLCD is a nonlinear device, the time domain analysis based on nonlinear Newmark method is employed to obtain the displacement, velocity and acceleration of different stories and TLCD. To illustrate the results, Kobe arthquake data is applied to the model. The results show that the soil type highly affects the suitable parameters of TLCD subjected to the earthquake oscillations. This study helps the researchers to better understanding of earthquake vibration of the structures including soil effects, and leads the designers to achieve optimized TLCD for the high-rise buildings
