Genetic algorithm-based optimization of a tuned inerter damper for structural seismic response reduction

This research examines a model of a Tuned Inerter Damper (TID) developed by the authors in minimizing vibrations in a five-story structure when exposed to seismic activity. The TID model is developed using MATLAB Simulink and tested on a 5-story building model when exposed to an earthquake signal. The TID model configurations were calibrated to match the primary vibration frequency of the building using established tuning approaches. Then, genetic algorithm optimization was employed to enhance the inertance parameter for better performance under earthquake excitation throughout all building levels. Time-based simulations were performed comparing different scenarios with the TID optimized system. The results demonstrated that implementing the developed model of TID lead to substantial reductions in vibration magnitudes over time, which confirmed the potential of the inerter in enhancing structural oscillations control.
