    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.

    Análisis comparativo del comportamiento sísmico de una estructura de hormigón armado de diseño convencional frente a un modelo con disipadores de energía tipo BRB y su incidencia en la relación costo/beneficio
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-01) Sánchez Arcos, Alex Francisco; Peñafiel Valla, Lourdes Gabriela
    For the present research work, a comparative analysis of the seismic behavior between a conventional system and a system with BRB-type energy dissipators was carried out in a 6-story building with a total area of 291.38 m2. The structure is located in the city of Ambato and is classified as essential according to the provisions of the Ecuadorian Construction Standard. The methodology of a nonlinear static analysis (Pushover) was extracted to evaluate the performance of each structural system based on an earthquake with a return period of 475 years, with an exceedance probability of 10 percent in 50 years. For the design of the structural elements, as well as the BRB energy dissipators, both national (NEC 15) and international standards were used: American Society of Civil Engineers (ASCE 7-16, ASCE 41-13), American Concrete Institute (ACI 318-14), American Institute of Steel Construction (AISC 341-16). Obtaining displacement results, derivatives of floors, optimal structural elements, seismic behavior and performance levels of the two structural systems under study.

    Análisis comparativo del desempeño sísmico en edificos de hormigón de mediana altura aplicando riostras de pandeo restringido en la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-09) Zamora Altamirano, Julio Santiago; Peñafiel Valla, Lourdes Gabriela
    For this research work we proceeded to perform a comparative analysis of the structural behavior for two types of systems: conventional and with the application of a modern system of seismic dissipation, in an 11-story building consisting of two elevators in an area of 400 square meters; The structure is located in the city of Ambato and was classified in special using the Ecuadorian Construction Standard. The methodology of a Pushover nonlinear static analysis was used to evaluate the performance of each proposed structural system based on a rare earthquake, which is usually the design earthquake with a return period of 475 years with a 10 percent probability of exceedance in 50 years. For the design of the structural elements of the building, as well as for the seismic dissipation system, national and international standards such as the Ecuadorian Construction Standard (NEC 2015), American Society Of Civil Engineers (ASCE 7-16, ACSE 41-13), American Institute Of Steel Constructions (AISC 341-16) were used. Giving us as results the displacements, floor drifts, system energy, behavior and performance levels of the two types of structures with the help of ETABS 2016 software.
