    Estudio de peligro sísmico determinista para las estructuras de Ambato sector la Universal ubicado entre las calles Bolivariana, Hipócrates, Jenofonte, Horacio, Real Audiencia y Pitágoras

    The present experimental work has been made with the purpose to evaluate the seismic danger existing at the area “La Universal” from Ambato city, through the method deterministic seismic danger. For the develop of the investigation the tectonic regime was define based on the area in analysis, was selected faults nearest and active to the study area, also was made the Standard Penetration Test (SPT), this test was done on five points of the area with the purpose to get kind of existing soil and through this information it was calculated the cutting wave speed (Vs30) to determinate the soil profile with the table provides by NEC-2015. Similarly, through the method of Wells- Coppersmith was calculate the Magnitude of the Moment Weight (Mw) for all failure selected, and through prediction equations of soil movement, we proceeded to calculate acceleration spectra for each fault, using an envelope, from that was determined a specific spectrum for the area, the same that is compared with NEC-2015. The determine spectrum generates greater accelerations with regard stablished spectrum in the NEC-2015 in a period 0.15 to 0.4 seconds, that established that structures will be affected, It determines that the spectrum influences to the structures that are in the area, through the investigation, was determined that structures under five floors, have more seismic threat.

    Estudio de peligro sísmico determinista para las estructuras del sector la matriz de la ciudad de Ambato”
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Civil, 2019) Rosero Bautista, Verónica Alexandra; Chérrez Gavilanes, Diego Sebastián
    To carry out the study it was necessary to use different research methods and techniques, in the initial stage information was collected on the evaluation of response spectra to the fault systems chosen with the spectrum proposed by the Nec-15, in the collection stage of data and obtaining results, descriptive research was used, after the experimentation stage, tests were carried out to determine the type of soil through the Standard Penetration Test (SPT), the NEC recommends performing 5 holes for the study of soils, so which were used GMPE's: Akkar and Bommer, Boore and Atkinson, Kanno, Youngs and Zhao.The results obtained were that according to the model of Akkar and Bommer is the most critical, since with this model was obtained the maximum acceleration for each of the faults, also in a certain interval of the period it exceeds the spectrum of the NEC-15 for the Ambato faults. The spectrum that generated the greatest response was that of the Ambato fault, because this fault has the smallest distance perpendicular to the 1.05 km study área.

    Desarrollo de una aplicación para determinar el espectro de aceleración específico en distintas zonas del cantón Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Civil, 2019) Moreira Lascano, Juan Pablo; Garcés Chávez, Juan Enrique
    The research work proposed below was carried out with the purpose of generating an application through a programming software, which allows specific acceleration spectra to be determined by using different Movement Prediction Equations (GMPEs) recommended by the Ecuadorian Standard of Construction (NEC-2015). The application is based on GMPE's for the tectonic regime that governs the city of Ambato (Cortical and Subduction). The seismic characteristics that are used by the GMPE's to generate the specific acceleration spectra are: Cutting Wave Velocity at 30 meters Depth Vs30, Magnitude of the Seismic Moment Mw, Type of Fault, Focal Depth, Distance closest to the surface projection of failure Rjb. and Depth of Fault H. The developed software minimizes the time used to determine the specific acceleration spectrum, since, as this is a repetitive process, it reduces the time used to prepare it manually. To determine the validity of the results obtained through the application developed, a comparison was made between the manual calculation and the calculation through the software developed; revealing a difference of less than 1% between the maximum acceleration values of the earth (PGA) obtained in each of the cases. In this way it was found that the application delivers accurate results in less time.
