Abstract
Los códigos actuales de diseño son cada vez más estrictos para el diseño de las estructuras que necesitan mantenerse operando continuamente durante un evento de terremoto. Las estructuras tales como hospitales, edificios gubernamentales especiales y aquellas que sirven de refugios están dentro de
esta categoría. Pese a esto, tales requerimientos si permiten grandes deformaciones debido a que los códigos actuales usan una carga lateral reducida que toma en cuenta el comportamiento inelástico, lo cual redunda en una gran cantidad de daño para la estructura. En esta investigación se evaluaron dos escuelas y un hospital tanto en el rango elástico como inelástico utilizando sus planos de construcción. En base a los resultados obtenidos del análisis elástico se proveyeron alternativas de rehabilitación para las estructuras que le permitieron mejorar su capacidad de resistir cargas laterales. El análisis no lineal permitió cuantificar el daño a estas estructuras al ser sometidas a un evento sísmico.
Current codes establish more stringent requirements for the design of structures that need to be operating continuously during an earthquake event. Structures such as hospitals, special government buildings and structures that will work as shelters are in this category. However, such requirements allow large deformations because current codes use a reduced lateral load that takes in account the inelastic behavior of the structure, which redounds in a great amount of damage for the elements. Two schools and one hospital were evaluated in this investigation in the elastic and non lineal range using their construction plans. Based on the elastic analysis results rehabilitation improvements were performed to the structures that allowed them to resist the lateral loads with minimum deformation. The no lineal analysis allowed to quantify the damage to these structures when they where under a seismic event.
