Estudio de peligro sísmico determinista para las estructuras del sector la Pradera, parroquia Celiano Monge, de la ciudad de Ambato provincia Tungurahua

Abstract

In the present research project, the vibration period was calculated for three type structures located in the study area. A deterministic spectrum was also obtained for this sector, expressed as the gravity acceleration Sa (g), to compare it with the spectrum of accelerations of the NEC-15 and verify the structural behavior of each of the structures selected from the study area. To determine this process, the following steps were taken: establish the tectonic regime based on the study area, select the geological faults that will affect the study area the most, based on the length of each fault, the magnitude of the Faults, by means of the standard penetration test, the Nspt was obtained to determine the average speed of the approximate Vs30 shear wave for the profile type, by means of parameters such as distance, source-site distance, focal depth, equations of Soil motion prediction attenuation obtaining acceleration spectra, by means of an envelope of all the acceleration spectra a specific spectrum of maximum accelerations is obtained, this spectrum is compared with the spectrum of the norm. The accelerations given by the specific spectrum in a period of 0,14 and 1,49 are greater than the accelerations obtained with the NEC-15 spectrum
