Item 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 LuisIn 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.Item Desarrollo de un software para el diseño de vigas y columnas metálicas de acero conforme a la normativa AISC 360-16(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2022-03) Zambrano Salazar, Luis Leonardo; Peñafiel Valla, Lourdes GabrielaIn the present research project, the graphical interface and the coding of a calculation software for the pre-design and design of steel beams and columns were carried out in accordance with the AISC 360-16 standard, through the use of a programming software and its tool guide. The software allows us to obtain pre-design sections for both beams and columns, which were verified in the design process, proven that they resist the requests to which they are exposed to the structure under analysis, all this is done by entering data such as: geometric configuration of the structure, load states and properties of the steel to be used. For the development of the software, it has been necessary to carry out a bibliographical investigation where the LRFD (Load and Resistance Factor Design) method is extended, for the design of steel beams and columns, which is approved by the American Institute of Steel Construction. (AISC 360-16) and the Ecuadorian Construction Standard (NEC 2015). Once the calculation method was determined, the algorithms necessary for the software coding were developed, once defined, the graphical interface of the same was elaborated. Once the development of the software was completed, a debugging of the programming code was carried out where the calculation algorithms were optimized to achieve a better and faster operation of the software. The validity of the developed program will be verified through a comparison of the results obtained through the software, manual calculations and a commercial program, obtaining an error rate of less than 0.8 percent, with which it was possible to verify that the calculation values obtained through the software developed in this research they are valid and reliable, thus achieving an optimization in the calculation time and precision in them, since being an automated software the human factor capable of committing involuntary errors during the manual process is eliminated. of calculation.Item Diseño estructural del edificio de posgrado de la Universidad Técnica de Cotopaxi para garantizar su correcto desempeño sísmico(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2021-09) Razo Taco, Jasmyn Abigail; Suquillo Ronquillo, Betzabeth JesseniaThis technical project aims to carry out the structural design of a building dedicated to educational activities in the postgraduate area of the Technical University of Cotopaxi, located in the city of Latacunga, to guarantee its correct seismic performance, taking into consideration the requirements of the Ecuadorian Construction Standard (NEC 2015). For the elaboration of this work, the bibliographic, deductive and analytical research method was applied, as well as descriptive, applied and explanatory research. Based on the technical analysis and architectural design provided by the institution, the design of a steel structure was carried out, for which a system of special concentrically braced frames (SCBF) was established and determined gravitational loads, overloads, seismic loads for a structure of special occupation and pre-designs of structural elements, parameters that allowed the structure to be modeled in a structural analysis and design software where the behavior of the same was observed by carrying out the linear analysis, in addition the structural elements and connections were designed. For the validation of the design carried out, the seismic requirements, drifts presented and design considerations that are specified in the NEC-SE-CG-15 NECSE-DS-15, NEC-SE-AC-15, AISC 360-10, AISC 341-10, ASCE-SEI 7-16, ASCE 41- 13, AISC 358-16. Finally, applying the methodology of FEMA 440, the non-linear analysis of the structure was carried out, evaluating its seismic performance using a return period of 2500 years, concluding that the structure will behave safely in the event of a seismic event.
