Abstract

The global propagation of tall building projects has occurred rapidly. Among the significant
challenges encountered by tall buildings are the issue of structural vibrations. Therefore, damping, as a phenomenon leading to the gradual dissipation of system energy and subsequent reduction in structural vibrations, Various damping technologies have been developed to dissipate structural vibrations. These include passive damping systems such as tuned liquid dampers (TLDs), emerges as a crucial factor in safeguarding these structures from excessive oscillations. Damping tools have recently seen advancements in the form of Tuned Liquid Dampers (TLDs). Traditionally constructed as rigid tanks filled with a specific quantity of water, this tool employs the dynamics of sloshing water upon activation. The application this system in mitigating undesired structural vibrations holds practical significance. The current study aims to investigate the effectiveness of TLDs in reducing structural vibrations due to seismic excitations. This involves the numerical simulation of structures with different TLD mass ratios to determine the most effective mass ratio.
