Smart base-isolation systems for enhanced seismic resistance in regions prone to earthquakes: A simulation study

The increasing frequency of seismic events highlights the need for improved seismic resistance in buildings. This study investigates the potential benefits of implementing smart base-isolation systems composed of base-isolation devices and Magneto-Rheological (MR) elastomers. The proposed system provides a semi-active solution to reduce the impact of earthquakes by adjusting its properties based on external stimuli. A smart base-isolation model was developed to simulate the behavior of MR elastomers accurately.Numerical simulations were conducted on a five-story building subjected to various earthquake loadings, demonstrating the efficacy of the system in reducing floor accelerations and inter-story drifts during near-fault and long-duration earthquakes over a broad range of magnitudes. The simulation results suggest that the proposed system could be an effective way to enhance the seismic resistance of buildings and mitigate the damage caused by future seismic events.The recent earthquake in Turkey and Syria, which occurred in February 2023, highlights the urgent need for developing effective seismic resistance strategies. Smart base-isolation systems could play a crucial role in enhancing the earthquake resistance of structures, potentially reducing the impact of seismic events on buildings and communities.In conclusion, by adopting innovative and advanced technologies, we can effectively prepare for and mitigate the impact of earthquakes on our communities. Such proactive measures are crucial in ensuring the safety and resilience of our built environment in the face of inevitable natural disasters.Keywords: earthquake-resistant building, smart base-isolation, MR elastomers, numerical study, seismic performance, semi-active system.
