Revisión de los espectros de desplazamientos de la Norma Ecuatoriana de la Construcción (NEC 2015) en base a los registros sísmicos de los terremotos más severos capturados.

Abstract

An investigation was carried out on the most severe seismic events that have occurred around the world, classifying them by their magnitude, impact and effects that they caused in their respective places of occurrence. Then, the information was searched about the stations and the seismic records generated from them. After this process, the displacement response spectra were generated with the help of a data analysis software. Once the corresponding data were available, graphs were made in which all the displacement response spectra graphics, generated for the North-South and East-West components, were unified. The next step was to generate displacement design spectra formulated and provided by the Ecuadorian Construction Standard NEC 2015, which were made for different seismic zones, soil types, regions and earthquakes with return periods of 475 years and 2500 years. From the above mentioned, displacement response spectra and displacement design spectra were unified in a single graph in order to generate comparisons and visualize the changes that were in the displacements depending on their period and the different characteristics that compose them.
