Análisis y caracterización dinámica de suelos, mediante el método combinado de “Columna resonante y Corte torsional cíclico”, para el estudio de la respuesta de sitio, del “bloque G”, ubicado en la Universidad Politécnica Salesiana, sede Quito, campus sur, 2022

Abstract

The Dynamic characterization of soils presents parameters of fundamental importance for the analysis of their behavior against dynamic loads; thus, it is the basis for a much broader study of the behavior of a structure against earthquakes when considering site response analysis or soil-structure interaction problems. This paper will deal with the application of the combined test of “Resonant Column and Cyclic Torsional” Shear, with the 31-WF8500 equipment, in 5 soil strata taken from “Block G” of the Salesian Polytechnic University, ranging from 0 to 10 meters, in order to obtain the graphs of “Shear Modulus Degradation vs Deformation”, as well as the “Damping Vs Angular Deformation”. The data obtained from 5 soil strata at different depths are described in detail. For which 3 clay samples were obtained in the first 3 strata from 0 to 8 meters (OL, CL, ML-CL) and 2 of sands for the last 2 strata from 8 to 10 meters (SM), from which all their physical-mechanical properties are obtained. The test is carried out with samples extracted in 2 and 3'' diameter Shelby tubes using the SPT test. In addition, a comparison of the dynamic parameters measured in the present study and those obtained by different authors in the literature is carried out.
