Resumen
El Ecuador se encuentra ubicado en la región denominada Cinturón de Fuego del Pacífico, en el cual presenta altas demandas sísmicas debido a los cambios continuos en la superficie del planeta por la interacción de placas tectónicas que han causado gran destrucción o daños irreparables en estructuras, en consecuencia, de la convergencia entre la placa de Nazca y la placa Sudamericana. En este proyecto de investigación se realiza un análisis usando los factores de la tabla Fa, Fs y Fd para cada tipo de perfil de suelo de la Norma NEC 2015, en el cual se considera las 4 regiones del Ecuador tomando en cuenta todos los cantones por provincia y se determina un valor promedio del coeficiente sísmico para cada tipo de perfil de suelo usando el software Excel, donde se obtuvo 6 mapas del coeficiente sísmico usando el software de información geográfica GIS y analizar su coherencia con el Mapa de Peligro Sísmico de la NORMA NEC-15 .
Ecuador is located in the region called the Pacific Ring of Fire, in which it presents high seismic demands due to the continuous changes in the planet's surface due to the interaction of tectonic plates that have caused great destruction or irreparable damage to structures, in consequence of the convergence between the Nazca plate and the South American plate. In this research project, an analysis is carried out using the factors of the table Fa, Fs and Fd for each type of soil profile of the NEC 2015 Standard, in which the 4 regions of Ecuador are considered, taking into account all the cantons by province and an average value of the seismic coefficient is determined for each type of soil profile using Excel software, where 6 maps of the seismic coefficient were obtained using the GIS geographic information software and their consistency with the NORMA Seismic Hazard Map was analyzed.
