Evaluación del comportamiento estructural de una edificación de mediana altura en acero mediante un diseño sismorresistente convencional y otro por medio del uso de aisladores sísmicos

Resumen

This research details a comparative analysis of the structural behavior of a mid-rise steel building in San José, Costa Rica, utilizing both conventional seismic-resistant design and an innovative approach with seismic isolators. Through meticulous study, it concludes that integrating seismic isolation systems is crucial in high seismic activity regions, not only for enhancing structural resistance but also for significantly reducing damage during earthquakes.

It is highlighted that, while current standards like those of the American Institute of Steel Construction are comprehensive regarding safety, there is a gap in the inclusion of advanced seismic isolation technologies. The research demonstrates that the use of seismic isolation optimizes the efficiency of steel elements, keeping them predominantly within the elastic range and reducing the need for energy dissipation.

This efficiency not only improves structural protection but also simplifies design and construction requirements. The findings reveal that structures with seismic isolation are lighter, more economical, and offer a substantial reduction in seismic force transmission. Moreover, there is a notable decrease in drifts and absolute accelerations, leading to greater safety and the possibility of immediate post-event occupancy, particularly relevant for essential structures like hospitals and emergency centers.

This study underscores the need for continuous updating and expansion of construction norms to include advanced analysis methodologies and seismic isolation technologies. The firm recommendation is made for detailed seismic hazard studies and the application of third-party reviews in essential structure projects, thus ensuring utmost safety and resilience.

This research validates seismic isolation as an efficient and cost-effective solution in seismic-resistant structure design. The findings of this study not only contribute significantly to the field of structural and seismic engineering but also mark a progression towards the construction of safer, more resilient, and sustainable buildings in high seismic risk regions.
