Evaluación de la estabilidad de sitio para la estructura de la unidad educativa Oscar Efrén Reyes perteneciente al distrito 18D03, cantón Baños

Abstract

In the present experimental project, an investigation is carried out with the purpose of evaluating the existing seismic hazard in the Oscar Efrén Reyes Educational Unit as well as in the houses surrounding the study area. For the research process, the tectonic regime was determined according to the analysis zone, the active faults near the study point were identified and used, in addition, four soil analyses were performed by means of the Standard Penetration Test (SPT), and from the data obtained, the shear wave velocity was calculated identifying the type of soil profile with the help of the table present in NEC 15. The data obtained were used in the ground motion prediction equations (GMPEs), resulting in the acceleration spectra for the five faults selected by each author, from which a specific deterministic spectrum was determined for the zone by means of an envelope, which was compared with the response established by NEC 15. The accelerations given by the deterministic spectrum of the structures in comparison with the spectral acceleration established by NEC 15 is higher considering that they are within the same time period interval.
