Seismic base isolators act as an intermediary in breaking the relationship of any dynamic effect that will be transmitted to the structure from the base. Against seismic loads, the isolators rapidly reduce the acceleration of the earthquake load with their unique mobility and provide an effective displacement control. The correct selection of parameters is important for isolators with certain damping limits in the evaluation of control performance. In this study, various distant fault earthquakes were excited as excitation to a single degree of freedom structure using an isolator with a damping limit of 30%. The damping and period of the isolator structure under seismic excitations were optimized to minimize the system acceleration, and the performance of reducing the structure motion in the critical earthquake record was recorded. For this purpose, the optimization process was carried out with the Teaching-Learning Based Optimization (TLBO) algorithm, which is a metaheuristic algorithm, and the algorithm performance was compared with the structure optimization study with sample isolators. When the results are examined, it has been observed that increasing the isolator mobility provides a good acceleration reduction optimization compared to similar metaheuristic algorithms.
