Estudio de peligro sísmico determinista para las estructuras del cantón Ambato – sector Huachi Loreto – barrio Ciudadela Oriente

Abstract

In the present experimental work, we use the determinist earthquake method to evaluate the structure who belong to “Ciudadela Oriente” neighborhood using the critic response spectre; also, we compare it with the spectre detailed in NEC-15. For the development in this investigation we select a zone who belongs to Ambato city, we also select a subduction failure and four near cortical failure, in these failures; we apply the relation Wells-Coppersmith to obtain the moment measure. Additionally, in the study area has been done five perforations that we use to classify the soils by the SPT essay, with this essay the medium speed of the cut wave Vs30 has been calculated and use it to stablish a soil type label. These parameters, in set with the epicenter and the focal deep, are used with the soil movement prediction equations to generate spectres, which ones were in an envelope to obtain a specific spectre. Giving as result a predominant spectre during a range period between 0.11 and 0.57 sec over the spectre detailed in NEC-15, the results stablish the two and five floors structures are being affected for this spectre. By the way, the tested structures present trouble to dispel seismic energy.
