Paper Title
Response Mitigation of Structures using Liquid Column Vibration Absorber Considering Real Earthquake Ground Motions

The performance of Liquid Column Absorber (LCVA) to mitigate structural vibrations considering different real earthquake time history data is investigated in this paper. To evaluate the significance of the parameters like mass ratio, frequency tuning ratio, length ratio, and area ratio, on the effectiveness of the LCVA for different earthquakes, a similar parametric analysis is performed using a time domain method. The result of the study shows that LCVA is very much effective in reducing the structural response to seismic excitations and the parameters play significant role in the performance of LCVA and some of them are also sensitive to the nature of the excitation. Keywords - Real earthquake time history, liquid column vibration absorber, vibration control, parametric study.
