Resumen
En el presente proyecto se realizó un análisis dinámico espectral, utilizando el reglamento de la Norma Ecuatoriana de la Construcción (NEC) en su capítulo peligro sísmico, para determinar el desempeño de la estructura ante eventos sísmico.
La estructura evaluada se implantara en la ciudad de Babahoyo, por lo cual se obtuvieron los datos de zonificación, el tipo de suelo, y los factores que se utilizan para la elaboración del espectro de diseño, como lo indica la Norma Ecuatoriana de la Construcción. Este análisis se lo realizo utilizando un modelado en el programa Etabs versión 2016, en el cual se obtuvo los periodos y la participación de la masa en los modos de vibración de la estructura, las derivas elásticas en cada piso, el peso total de la estructura para luego calcular el cortante estático teórico y compararlo en su 80% con los cortantes dinámicos en los sentidos X y Y.
Se revisó si la estructura cumplía con el criterio columna fuerte viga débil, el cortante en las caras de los nudos y el cortante en la vigas, llegando a la conclusión de que no tenía un buen desempeño por lo que habrá que revisar las secciones de los elementos estructurales y sus áreas de acero.
In the present project a dynamic spectral analysis was carried out, using the regulation of the Ecuadorian Construction Standard (NEC) in its seismic hazard chapter, to determine the performance of the structure before seismic events. The evaluated structure will be implemented in the city of Babahoyo, for which the zoning data, the type of soil, and the factors used for the preparation of the design spectrum were obtained, as indicated by the Ecuadorian Construction Standard. This analysis was carried out using modeling in the Etabs version 2016 program, in which the periods and the participation of the mass in the modes of vibration of the structure, the elastic drifts in each floor, the total weight of the structure were obtained. to then calculate the theoretical static shear and compare it in its 80% with the dynamic shear in the X and Y directions. It was checked if the structure complied with the criterion column strong weak beam, the cutting in the faces of the knots and the cutting in the beams, arriving at the conclusion that it did not have a good performance reason why it will be necessary to review the sections of the structural elements and their steel areas
