Resumen
El trabajo de titulación consistió en realizar la evaluación del desempeño sísmico de una estructura de hormigón armado de 4 niveles ubicada en la Ciudad de Guayaquil, sector Las Acacias 1, tiene geometría irregular, compuesta por vigas chatas y columnas de poca sección, construida en los años 90. El objetivo fue determinar su desempeño ante la aplicación de cargas sísmicas, se realizó un modelo matemático tridimensional en el Software Etabs para verificar el comportamiento estructural de los elementos vigas y columnas, se verificó el criterio de columna fuerte-viga débil, derivas, periodo fundamental, cortante basal y masa participativa que cumplieron con las especificaciones de la NEC-15; con el uso de modelos matemáticos en 2D se determinó el nivel de desempeño de la estructura a través de los Análisis no lineales Estático (Pushover) y Dinámico (Time History) usando los criterios del ASCE 41-13 y el Comité Visión 2000.
The degree work consisted of evaluating the seismic performance of a 4-story reinforced concrete structure located in the city of Guayaquil, sector Las Acacias 1, with irregular geometry, consisting of flat beams and columns of small section, built in the 90's. The objective was to determine its performance under seismic loads. The objective was to determine its performance under the application of seismic loads, a three-dimensional mathematical model was made in Etabs software to verify the structural behavior of the beams and columns elements, the criteria of strong column-weak beam, drifts, fundamental period, basal shear and participatory mass were verified to comply with the specifications of the NEC-15; With the use of 2D mathematical models, the performance level of the structure was determined through nonlinear Static (Pushover) and Dynamic (Time History) analysis using the criteria of ASCE 41-13 and the Vision 2000 Committee.
