Resumen
La normativa actual vigente en el Ecuador en lo que a diseño estructural se refiere es cada vez más estricta para el diseño de las estructuras esenciales como para estructuras no esenciales. Las estructuras tales como hospitales, edificios gubernamentales especiales y aquellas que sirven de refugios están dentro de esta categoría. Pese a esto, los requerimientos expuestos en tales normativas si permiten grandes deformaciones debido a que los códigos actuales usan una carga lateral reducida que toma en cuenta el comportamiento inelástico de las estructuras, lo cual provoca una gran cantidad de daño para la estructura. Esta investigación se enfoca en la evaluación sísmica del edificio Torre Medica tanto en el rango elástico e inelástico, utilizando los datos estructurales obtenidos de los planos de construcción a partir de los cuales se obtuvieron los detalles estructurales. En base a los resultados obtenidos del análisis elástico se proveyeron alternativas de protección sísmica como lo son los sistemas de disipación de energía y el sistema de aislamiento sísmico, que le va a permitir mejorar su capacidad de resistir cargas laterales. El análisis no lineal permitirá cuantificar el daño a la estructura al ser sometida a un evento sísmico. Finalmente, con estos resultados se realizó la comparación costo beneficio de la implementación de los sistemas de protección sísmica.
Current regulations in Ecuador in terms of structural design are increasingly strict for the design of essential structures as for non- essential structures. Structures such as hospitals, special government buildings and those that serve as shelters are within this category. Despite this, the requirements exposed in such regulations if they allow large deformations because the current codes use a reduced side load that takes into account the inelastic behavior of the structures, which causes a great amount of damage for the structure. This research focuses on the seismic evaluation of the Torre Medica building both in the elastic and inelastic range, using the structural data obtained from the construction plans from which the structural details were obtained. Based on the results obtained from the elastic analysis, seismic protection alternatives were provided, such as the energy dissipation systems and the seismic isolation system, which will allow it to improve its ability to withstand lateral loads. The non-linear analysis will allow to quantify the damage to the structure when being subjected to a seismic event. Finally, with these results, the cost-benefit comparison of the implementation of seismic protection systems was performed.
