Item 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 AgustínThe 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.Item Estudio del comportamiento estructural de una edificación de 4 pisos de estructura metálica con aisladores sísmicos, en función de la dirección de la losa colaborante(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2024-05) Jiménez Gavilánez, Alex Daniel; Peñafiel Valla, Lourdes GabrielaThis research arises from the uncertainty of whether the variation of the collaborating slab influences the behavior of the structure when it has base seismic isolators, with the purpose of identifying which would be the best option when choosing the direction in which This structural element would be placed and provide a guide for subsequent analyses. For this reason, in this research, the modeling of a structure was carried out using structural simulation software, taking into consideration the seismic specifications of the Ecuadorian Construction Standard (NEC-2015), to begin this degree work, it was located a building in the city of Ambato to obtain the site factors, it also has regularity in plan and elevation, with a level of importance for essential buildings, this building has an area of 540 square meters and a height of 14 meters; Once the structure was stabilized with the collaborating slab in the direction of the abscissa, the direction itself was varied perpendicular to the first, that is, parallel to the ordinates, thus creating a second structure to study. For the structures already stabilized by gravity loads, the calculation of the seismic isolators that were located at their bases was carried out. In the case of this study, an elastomeric isolator with a lead core or LRB type was considered, whose Data were entered into the structural simulation software for processing and analysis. Data on floor drifts, vibration periods, and displacements caused by the action of the design spectrum obtained with the parameters of the NEC 2015 and the time-history (TH) analysis based on the seismic records of the earthquake were obtained from the simulated structures. occurred in the city of Pedernales in 2016, with these data it was possible to carry out a comparative analysis of the behavior of both proposed structures.Item Evaluación de la vulnerabilidad sísmica de edificaciones de estructuras metálicas de la parroquia La Península, Ambato, Ecuador: Propuesta de reforzamiento estructural de una edificación representativa(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2024) Pérez Castro, Víctor Hugo; Chérrez Gavilanes, Diego SebastiánThe parish of La Peninsula in the city of Ambato is located in an area of high seismic hazard in Ecuador. This parameter, together with the vulnerability of the buildings and the level of exposure, represents the level of risk that could occur in the face of these events. Seismic vulnerability is a magnitude that allows quantifying structural damage, failure modes and resistance capacity under the action of an earthquake, based on the characteristics of the building such as the type of structural system, irregularities in the floor plan, elevation, frequency of maintenance, application of regulations, construction codes and other parameters that are controllable, to provide an overview of the degree of vulnerability and seismic risk index of the buildings. The first step was to identify the buildings in which the main component was the metal structure, and from there, with the help of the forms proposed in the FEMA P-154, NEC 15 and FUNVISIS standards, it was finally possible to establish the degree of vulnerability of these buildings. For the interpretation of the results, the NEC 15 and AISC 360 criteria were used because the buildings found in the area were of traditional moment frames. A representative building in the area was selected to evaluate in detail the seismic vulnerability, in this case a linear static and spectral modal analysis was performed,
