    Diseño y simulación de una cubierta en estructura metálica para ser usada en estacionamientos vehiculares en base a la normativa NTE INEN 2248
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2025-02) Dueñas Beltrán, Justin Leonardo; Yunapanta Velastegui, José Luis
    To obtain normalized information about the cantilevered roof, the main objective of this technical project is to design and simulate a metal roof intended for vehicle parking, in compliance with the Ecuadorian standard NTE INEN 2248, which establishes the minimum dimensions required for vehicle parking spaces. Additionally, the types of loads affecting the roof were determined based on Ecuadorian construction regulations. To achieve this, an analysis of different metal roof alternatives was carried out, selecting the one that offers the most efficient design in terms of stability, strength, and cost. The design was based on preliminary analyses with different structural elements and variations in load analysis. The evaluation included a detailed assessment of the various load conditions acting on the structure, such as dead loads, live loads, seismic loads, and wind loads, according to the specifications of Ecuadorian construction standards. The values corresponding to these loads were determined through precise calculations, ensuring the structure maintains adequate stability and safety. For the structure, A36 steel profiles were selected due to their wide availability in the market and excellent mechanical properties. The modeling and simulation of the design were conducted using specialized structural design software, which made it possible to evaluate the roof's behavior under various load conditions. This analysis ensured that stresses and deformations remain within the ranges allowed by the standards, minimizing the risk of structural failures. This comprehensive approach ensured a safe, efficient design fully aligned with the current technical standards in Ecuador.

    Estudio y análisis del proceso de fabricación de cerchas de acero tipo HOWE para fortalecer la productividad de la empresa FYMSA, del cantón Salcedo–Ecuador
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2024-02) Redrobán Amores, Luis Alfredo; Yunapanta Velastegui, José Luis
    In the search for new design alternatives for the construction industry, it is crucial for mechanical engineers to understand improvement criteria for a thorough analysis of metal structures. Interpreting regulations is a challenge that generates problems in the development of these projects, leading to non-compliance with standards, arbitrary actions, and erroneous decisions that have, in some cases, resulted in damage to infrastructure and compromised safety. Therefore, this research is experimental in nature, and the following hypothesis was proposed: the use of Howe-type trusses in FYMSA company is feasible as an alternative in the construction of industrial warehouses, considering their design, fabrication, and assembly. A comparative analysis was conducted with the trusses commonly used in the construction of industrial warehouses. Through qualitative analysis, the situation in the company was described, and deficiencies in the manufacturing process were identified. To determine the effectiveness of using Howe trusses, a non-linear Pushover analysis was performed, determining the ductility of the structure. It was found that the elements, when subjected to critical seismic loads, did not experience rupture, and the ultimate strength (Sut) limit reflected in the performance curves was extended by 80 percent less than Warren-type trusses. As a result, it was determined that the use of Howe-type trusses is feasible.

    Diseño y construcción de un JIG de ensamble de anclajes y plataforma en el proceso de fabricación de estructuras metálicas para buses interprovinciales modelo Silver Plus-Glass en chasis Hino AK de la carrocería Patricio Cepeda de la ciudad de Ambato, periodo octubre 2016 – marzo 2017
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica, 2017-07) Durán Caguana, John Jairo; Peña Jordán, Francisco Agustín
    This research project was carried out because Patricio Cepeda a company dedicated to the manufacture of buses does not have a matrix or JIG for the assembly of anchors and platform, resulting in alterations in measurements already established on the planes of the body. We collected information on assembly dies for metal bus structures as well as analyzed the current process of manufacturing anchorages and platform for interprovincial buses Silver Plus-Glass. This way to helped to select the best alternative solution that involved the optimization of materials and time as well as to facilitate the process of assembly of anchors and platform to the frame of the chassis, knowing that the bodies with greater demand are interprovincial models Silver Plus and Glass. With the knowledge and identification of the parts that conformed the matrix, the mechanical design of each one of them was carried out, through manuals, calculations and normative studies, the matrix was modeled in a design software. Finally, the matrix for the assembly of anchors and platform for the HINO AK chassis is elaborated, at the same time, performance tests were carried out to guarantee the correct performance of the matrix.

    Estudio del comportamiento del acero A36 mediante ensayos de tracción para determinar fallas en elementos estructurales, mediante la norma ASTM E-8
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánica., 2012) Guzhñay Miranda, Fernando Mesias; López Villacís, Gonzalo Eduardo
    El presente proyecto de investigación está orientado en proporcionar a los estudiantes de la Carrera de Mecánica de la Facultad de Ingeniería Civil y Mecánica, una idea acerca del tipo de fallas que pueden ocurrir en elementos sometidos a tensión y del comportamiento del acero estructural A36 en dicha condición. Para lo cual se tuvo que construir una máquina la que ayudará al estudiante a familiarizarse con las propiedades mecánicas de los diferentes tipos de acero, además podrán realizar ensayos de tensión que les permitirá tomar una mejor decisión al momento de seleccionar materiales, y dictaminar criterios razonables acerca del tipo de fallas que ocurren más frecuentemente en el acero antes mencionado. El estudio se basó en la realización de 34 ensayos de tensión en probetas normalizadas de tipo cilíndricas y de tipo rectangular, estipulado en la norma ASTM E-8, mediante los cuales se pudo ir observando el comportamiento del acero al ser sometido a fuerzas de tensión. Para obtener una mejor visualización tanto de la deformación de las probetas, así como también de las tres zonas características de la curva esfuerzo-deformación, la velocidad a la que se debe realizar el ensayo debe ser baja. Los resultados obtenidos tanto de ensayos de tensión así como de ensayos metalográfico fueron comparados con valores obtenidos en catálogos y gráficas obtenidos de empresas y los tabulados en libros, llegando a la conclusión, que los valores obtenidos prácticamente se encuentran en los rangos de valores aceptables.
