Abstract
Tuned Liquid Damper (TLD) is passive energy dissipation device that reduce the vibration of structure using sloshing force of liquid. Energy dissipation performance of TLD is affected by behavior of liquid, therefore, to suggest more accurate TLD numerical model, depth ratio and amplitude of excitation that change the behavior of liquid should be considered. As TLD numerical model, equivalent TMD model that substitute TLD to TMD which has same energy dissipation performance is widely used. Equivalent TMD model that suggested by precedent studies only considers amplitude of excitation, therefore, to predict the energy dissipation performance of TLD more accurately, TLD numerical model which consider the behavior change of liquid caused by depth ratio is needed. In this study, TLD numerical model according to the depth ratio and amplitude of excitation is suggested. Shaking table experiment is conducted to measure the energy dissipation response of TLD. TLD dynamic characteristics regression equation based on shaking table experiment is suggested, and it is applied to equivalent TMD model. To verify the accuracy of suggested TLD numerical model, precedent structure with TLD experiment results and analysis results applying suggested TLD numerical model and precedent TLD numerical model are compared.
