EVALUACIÓN DE LAS PROPIEDADES DINÁMICAS DEL SUELO DE GUAYAQUIL Y SU RESPUESTA ANTE EXCITACIONES SÍSMICAS

Abstract

This thesis describes the results of the field research and the numerical analysis of the dynamic response of the site for the Quito Avenue, downtown area of Guayaquil. The purpose of this study is to establish an adequate geotechnical characterization of the study site, based on exploration techniques, in order to subsequently discover the seismic response trend and be able to identify all the most influential parameters in this area. As a result of the characterization the methodology imposed by Yoshida (2015) was developed for the dynamic analysis of the site response, which is influenced by the behavioral properties of the stratum, as opposed to the action of external dynamic loads. These analyzes have been incorporated into computer programs such as DEEPSOIL and QUAD4M, by the finite element method. Results of LDI were obtained in order to predict the movements in the surface of the land for the construction of response spectra for design; in such a way that the results shown in this work can be useful in the design of structures that are planned to be built on the same body and whose lithological profile resembles the typical ones proposed in the geotechnical microzonification of Guayaquil.
