Estudio de peligro sísmico determinista para las estructuras del cantón Ambato – sector Huachi Loreto - barrio El Buen Pastor

Abstract

The present research work starts from the tectonic recognition capable of producing a movement of the terrain affecting the study area, for which information from studies carried out by the NeoTec was used. The soil analysis was carried out by means of the SPT test which was applied in 5 points, 4 perimetral and 1 central, thanks to this it was possible to determine the type of existing soil with which the Vs30 wave velocity was calculated. With this information, the characteristics of each fault were analyzed, including the type of fault, its seismic activity and the distance closest to the projection on the fault surface was calculated, all these parameters together with other criteria were essential to select the most dangerous potential failures. Subsequently, all these particularities were used in the Attenuation Equations, chosen according to the tectonic regime of Ecuador. Finally, it was possible to obtain a specific spectrum of maximum accelerations for the study sector, which proceeded to compare the specific Spectrum with the NEC Spectrum presented by the Ecuadorian construction regulations. The result of this comparison presented a critical interval in which the Specific Spectrum exceeded the acceleration values of the NEC Spectrum. Finally, the comparison is also presented with the results of a static and dynamic linear analysis in the structural behavior of three representative buildings of the sector, each with different geometric characteristics.
