摘要

Base isolation of structure has emerged as one of the most convenient methods of improving structural stability during earthquake excitations. The technique has been successfully implemented in many designs and has proven effective in mitigating the adverse effects of seismic shaking. The current article discussed the literature on the base-isolation technique's understanding, application, sustainability for future generations, and recent developments. The review examined multiple isolation technologies, such as elastomeric bearings, friction pendulum systems, and hybrid approaches. Particular attention was given to using recycled rubber from abandoned tires, illustrating its dual function in earthquake mitigation and environmental sustainability. Research indicated that integrating rubber–soil composites might diminish peak ground acceleration by 60–70%, thus improving seismic performance. The document emphasized the significance of soil–structure interaction in base-isolated systems, particularly in sandy soils susceptible to amplification and liquefaction. Moreover, incorporating hybrid isolators that merge elastomeric and sliding mechanisms markedly enhanced seismic performance by diminishing lateral displacements. The research highlighted the necessity for site-specific isolation designs that account for local seismic demands and soil conditions to maintain structural integrity during earthquakes. Finally, emerging materials and isolation techniques, like rubber–soil composites and geosynthetic isolators, provided improved damping and energy dissipation capabilities, fostering sustainable seismic protection solutions.
