Análisis de interacción suelo - estructura del edificio del bloque G de la Universidad Politécnica Salesiana, Sede Quito, Campus Sur, mediante la norma NIST GCR 12-917-21 - GAZETAS

Abstract

The objective of this research is to determine the behavior of the structure "Block G" of the Salesian Polytechnic University before a more realistic soil-structure analysis, through the application of equivalent springs in each of its six degrees of freedom. For the physical properties of the soil, calculations were taken from a study previously carried out by Jaramillo and Naranjo [19]. NIST GCR 12-917-21 is used to understand and calculate spring stiffness values for each degree of freedom. The model made in SAP2000 software allows us to calculate the resulting values of basal cut, drift and period of the structure, which will be compared between a rigid base and a flexible base. For the elastic spectrum and the load combinations applied to the software modeling, the NEC (Ecuadorian Construction Regulations) was used, and to obtain a response under seismic loads.
