Comparación de la respuesta dinámica de sitio usando los modelos: equivalente lineal en Pro-Shake 2.0 y no lineal en Deep Soil v 7.0, aplicado en el subsuelo del edificio “Bloque G” de la Universidad Politécnica Salesiana, Campus Sur, SedeQuito

Abstract

The study is focused on the analysis of the dynamic response of the site, specifically of “Block G” of the Salesian Polytechnic University (UPS), which is located in the Chillogallo sector of the city of Quito-Ecuador. Through modeling in the Pro-Shake 2.0 and Deep Soil 7.0 programs, the Linear Equivalent and Non-Linear methods are applied respectively. From which dynamic response spectra are obtained for the four categories of seismic hazard, according to the NEC-SE-DS 2015, according to the Seismic Hazard chapter. This research is substantial for future analyzes related to soil-structure near the site. As input data, there are seismic records (seed earthquakes), with seismic-tectonic characteristics similar to the study site, obtained from the PEER Ground Motion Database, and are adjusted to instrumental records for each threat condition according to the regulations. In addition, there are investigations of the subsoil of the study site such as: geotechnical and geophysical properties at different depths and which are entered into the programs. To evaluate the dynamic response of the site, a standard mean septum and standard deviation of each analysis are obtained, they are compared between both methods: linear and non-linear equivalent, it is also compared with the response spectrum according to it’s category of the NEC-SE standard. -DS 2015, which are typical of the subsoil on which the building is founded.
