Análisis de respuesta de sitio en el sector de la Universidad Politécnica Salesiana ubicada en la parroquia de Chillogallo del cantón Quito, usando modelos numéricos de campo libre, propagación de onda bidimensional y tridimensional, empleando el software midas GTS NX

Abstract

The research was carried out with the objective of analyzing the site response in the Salesian Polytechnic University sector to the south of the city of Quito, elaborating a comparison of the results obtained in the Midas GTS NX software with one, two and three-dimensional models, for four categories of seismic hazard, according to NEC 2015, Seismic Hazard chapter. Traditionally, to evaluate the site response, one-dimensional models are used, however, the methods of elements and finite differences evaluated in two and three-dimensional models are suitable to generate dynamic analyzes, using constitutive models that simulate the behavior of the soil when it is subjected. at cyclical loads. Among the input data are: the seed earthquakes obtained from the PEER database, geomechanical and geophysical data, provided by the Metropolitan Public Company of Quito. The results provided by the site response analysis (ARS) are: surface accelerograms, response spectra, acceleration profile, displacement and angular deformation, among others.
