The use of an electromagnetic-tuned liquid column inerter, known as ETLCDI, for mitigating the seismic response in a nuclear containment structure has been studied. The optimization of the structure incorporating the device has rarely been reported. The recently introduced enhanced version of the traditional liquid column inerter, called the ETLCDI, has been designed to meet the demanding requirements of engineering applications. This study explores the parameters and seismic analysis FPS-based structures that incorporates ETLCDI devices. Numerical method is used to optimize the parameters of the two components of the structure, which will minimize the variations in the seismic response. The results are based on the analysis of the stationary stochastic conditions under the influence of the FPS system’s nonlinear damping. This study thoroughly examines the effects of ETLCDI on a FPS-isolated framework. The numerical analysis of the structure is performed on a 2-DOF FPS-isolated framework that is equipped with an optimal ETLCDI. It has been found that the optimized ETLCDI can effectively address both the superstructure and base floor responses during severe seismic events.
