Item Estudio de pórticos arriostrados concéntricamente en V, V invertida y arriostramiento en K y su incidencia en el diseño de un edificio en acero de 7 pisos(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica. Maestría en Ingeniería Civil con Mención en Estructuras Metálicas, 2022-03) Salinas Villegas, Edisson Xavier; Espín Lagos, Segundo ManuelIn this research paper, a comparison was made between three types of bracing: in V, in Inverted V and in K of a 7-story building with the possibility of applying it in our environment as it is in the city of Ambato and also so that can be used at the national level since both national and American regulations were used. The pre-designs of the structural elements were made, both for the columns, main and secondary beams, collaborating plate, and the bracing elements to then carry out their respective design, first checking their compactness and slenderness in each of their elements. Through the use of finite element software, each of the structural elements was modeled, entering properties and specifications to its elements, a static and dynamic analysis was carried out, for which the load combinations were defined, and also the load spectrum. design, as well as the configurations of the structure in plan and elevation, in addition to the seismic zone according to the project that is being investigated, all this so that the 7-story structure is earthquake resistant and each of the checks stipulated by the Ecuadorian Construction Standard (NEC 2015). Comparisons were also made with the three different types of bracing and the price of the structure was analyzed. Finally, it was concluded that the best type of structure was the inverted V bracing, because it has a lower drift than the previous two with values less than two percent and has a good structural behavior compared to the other checks carried out as in the dynamic analysis that complies with a percentage greater than 80 percent, the rotational analysis less than 30 percent in both X and Y; and the participation of the mass greater than 90 percent.Item Evaluación funcional y estructural del pavimento de la vía Manuelita Saenz desde la intersección con la av. Quiz Quiz hasta la intersección con la av. José Peralta(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2019) Salinas Villegas, Edisson Xavier; Portilla Yandún, Favio PaúlThe purpose of this technical project is to carry out the evaluation of the operation and structural conditions of the pavement of one of the main collector roads located south of the city of Ambato. The thesis began with the determination of the TPDA through a traffic analysis through the realization of counts and categorization of the vehicles that circulate on the road. For the functional evaluation of the pavement, the PCI (Pavement Condition Index) method was used, which is based on a visual classification of the faults of the tread layer of the pavements for their respective assessment quantitatively according to the level of damage that has the same. To complement the above information, the measurement of deflections in the pavement was carried out through the Benkelman beam to verify compliance with the admissible deformations. Additionally, a soil study investigation was carried out, it was discovered that the properties of the particle layer of the pavement structure complied with the specifications proposed by MTOP. Finally, in the study of asphalt concrete, the percentage of bitumen of several samples taken from two sections of the track was obtained. It was determined that in the old asphalt concrete the percentage of asphalt is lower than the optimum while the repaved section meets the required specifications Finally, this thesis is concluded with a budget of the most deteriorated sections.
