Abstract
The objective of this investigation is to analyse the Tuned Liquid Damper (TLD) and Column Tuned Liquid Damper (CTLD) systems. These systems utilise the motion of liquid in a rigid container to modify the dynamic characteristics of a structure and mitigate vibration energy during seismic activity. A three-story edifice was constructed for this specific purpose and subjected to rigorous vibration testing. The top floor has separate installations for TLD and CTLD to accommodate different frequencies. A TLD (Tuned Liquid Damper) and CTLD (Coupled Tuned Liquid Damper) are devices that utilise water contained within a container, typically situated atop a building, to mitigate the displacement of the system when exposed to external forces. Experimental observations were conducted on a scaled model of the structure equipped with Tuned Liquid Dampers (TLD) and Connected Tuned Liquid Dampers (CTLD) to evaluate their performance under seismic excitation. The rectangular-shaped Tuned Liquid Damper (TLD) and Coupled Tuned Liquid Damper (CTLD) are subjected to controlled uniaxial shake table testing to assess their performance across different frequencies, while considering varying mass ratios. The assessment of TLD and CTLD effectiveness is based on the reduction in the response of the structure. The accelerometer utilised in the experiment is employed to quantify the acceleration of the structure under investigation in the presence and absence of a Tuned Liquid Damper (TLD) and a Controllable Tuned Liquid Damper (CTLD) while being exposed to vibrations.
