Estudio de peligro sísmico determinista para las estructuras del sector de la ciudadela El Dorado de la parroquia Huachi Chico, de la ciudad de Ambato provincia de Tungurahua

Abstract

In this research work, acceleration spectra were generated by using the GMPE's Movement Prediction Equations for Cortical Regime and Subduction, which is the tectonic regime of the study area, based on the most representative seismic characteristics such as: Cutting Wave Velocity Vs, Type of Fault, Seismic Moment Moment Magnitude Mw, Focal Depth and the closest distance to the projection on the surface of the Rjb fault. With this we obtained a specific spectrum of the area in which the maximum accelerations calculated in the different periods are presented, the same one that when compared with the spectrum provided by the NEC-2015 results in two critical intervals in which the accelerations exceed the accelerations proposed by the regulations. The demands of the specific spectrum were compared with the demands of the regulations, by modeling structures with the main characteristics of buildings in the sector, highlighting a sub-dimensioning of structural elements of the sector when estimating the seismic load with the standard.
