Determinación de acelerogramas reales para su empleo en los análisis dinámicos de las estructuras de edificaciones en la ciudad de Puyo

Abstract

The city of Puyo has a population of 36,659 inhabitants in an area of 87. 67 km2, constituted with 82 percent of clay soil and considering that Ecuador is a country of high seismic movement for being between two tectonic plates, the Nascar and the South American plate, the present study was focused on the search of real accelerograms belonging to seismic events whose characteristics comply with the conditions of magnitude, type of fault, distance to the fault point and soil effects of the study locality, according to its seismicity and seismicity, the distance to the point of failure and the soil effects of the study locality, in accordance with its seismicity and spectrality specified in the Ecuadorian Construction Norm (NEC), in addition, 7 computational routines were generated that allowed the treatment, processing and analysis of the same, in turn the chosen spectra were compared with two different types: design elastics for a seismic return of 475 and 2500 years for buildings of between 1 to 6 stories of structural elevation between their fundamental periods of the building of 0. 2T and 1.5T with which scaled accelerogram spectra were obtained that complied with Ecuadorian regulations and that in the future could be used in dynamic design studies for multilevel steel structures to be projected in the city of Puyo.
