    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 Manuel
    In 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.
