Investigation of the Effect of Maximum Height for Tuned Liquid Damper Optimization

Liquid dampers are damping devices that provide structural control by moving a spring and a container with a liquid mass under dynamic loads by sloshing the liquid. For the control of structures under external loads, tuned liquid dampers take advantage of the dimensions of the tank and the sloshing of the liquid. The tank geometry is optimized to increase the control efficiency of the damping tank. Within the scope of the study, in the design optimization of a tuned liquid damper (TLD) containing water, the change of the optimum diameter according to the maximum design limit change given for the tank height was examined. For this purpose, a cylindrical TLD device was placed on a single degree of freedom structure under seismic excitation and the tank geometry was optimized for different height limits. Jaya Algorithm, a nature-inspired metaheuristic algorithm with a simple one-step structure, is used in the optimization process. As a result of the investigations, it is observed that in TLD optimization, tank height increase does not significantly improve TLD performance.
