Building-like structures should be taken under control to reduce vibrations under dynamic effects such as earthquakes, to extend the useful life of building elements and to achieve goals such as life safety and comfort. For this purpose, passive, semi-active and active control systems are used for structures. Among these systems, Tuned Mass Dampers (TMD), which are passive control devices, are generally used in high-rise buildings but are also preferred to protect artifacts in historical buildings. In this study, parameter optimization of mass dampers will be done by using various metaheuristic algorithms, and the performance of these algorithms will be compared. In the optimization methodology, time-domain analysis results are taken as objective function by considering the stroke limitation as a design constraint to find optimum design variables. As a result, the metaheuristic-based methods are effective to consider the real problem for multiple degrees of freedom system in the time-domain analysis as an advantage to classical methods.
