    This technical project has as main objective the calculation and dimensioning of an isolated photovoltaic system to supply electricity to single-family homes that have limited resources from the Atahualpa parish, Ambato canton. It is desired that with the development of this type of projects the population is encouraged to search for and implement renewable energies that contribute to stop the negative global impact that several traditional practices of electric power generation are causing. To determine the components of the isolated photovoltaic system, a survey was carried out on 54 low-income houses belonging to the aforementioned parish. Once the monthly energy consumption had been determined, the housing was classified according to what is established in the Tariff Schedule for electric distribution companies for the period January - December 2020, issued by the electricity regulation and control agency, thus obtaining 3 types of housing , including a type house called survey which presents an energy demand equal to 8.70 kilowatt hours per day. To size the components, it was necessary to obtain the total monthly average daily irradiation value on an inclined surface, for which the meteorological data exposed by different specialized software were used, the irradiation value obtained by the Lui and Jordan Method is 3,887 kilowatt hours. per square meter per day with a solar panel inclination equal to 10 degrees. The components calculated for the Survey House are as follows: 10 solar panels connected in parallel with a nominal power of 350 watts, 8 batteries connected in parallel with a nominal capacity of 150 amp hours, 1 voltage regulator capable of satisfying a current of input and output of 89.75 amps and 24.07 amps respectively, 1 inverter with continuous power of 1500 watts with the capacity to satisfy 520 watts. The results for said house are presented since it is the one that most closely matches the reality of the sector, the total cost of the isolated photovoltaic system includes general construction items, the value of the components of the isolated photovoltaic system, the metal support structure and labor is $ 9908.25

    Diseño sismorresistente de un edificio de 4 plantas en estructura metálica con un subsuelo en hormigón armado ubicado en la ciudad de Quito
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2024-09) Quintana Vásconez, Roberto Sebastián; Peña Jordán, Francisco Agustín
    The present thesis shows the structural design of a project located in a high seismic activity zone, with particular focus on seismic safety and compliance with applicable regulations such as AISC 341, AISC 360, AISC 358, NEC 2015, and ASCE 7-16. Based on previous geotechnical studies, a detailed analysis of soil conditions and expected loads was conducted to ensure a solid foundation for the structure. This analysis enabled the identification of the necessary seismic parameters to adapt the structural design to the specific characteristics of the terrain and ensure stability against seismic movements. During the project development, specialized software was used to perform structural modeling. Through these programs, seismic loads were precisely simulated, analyzing both the stresses and deformations that the structure could experience. This approach optimized the structural behavior, ensuring an adequate distribution of stresses and minimizing inter-story drifts and lateral displacements at each level. The results demonstrated robust structural performance under the seismic demands of the site, highlighting the implementation of cruciform steel columns. This structural solution maximized the building's efficiency, leveraging its high moment of inertia, which is essential for resisting lateral loads. Finally, the validation of the design parameters confirmed compliance with seismic design codes, ensuring that the building can withstand the expected seismic demands without compromising its safety or functionality. This comprehensive approach has allowed the development of an optimized structure that meets local requirements, providing a viable and safe solution for high seismic risk conditions.
