Resumen
La presente investigación tiene como finalidad evaluar el desempeño sísmico de una edificación de 9 niveles de hormigón armado, cuyo sistema estructural es aporticado con una albañilería no reforzada. Considerando las características y propiedades de las secciones y materiales que conforman la estructura, para lo cual se procedió a modelar por medio del programa ETABS. Posteriormente se realizó un análisis estático no lineal tipo Pushover donde se determinaran las fuerzas cortantes y los desplazamientos laterales asociados a éstas; además se obtiene la curva de capacidad de la estructura establecida , mediante esta curva de capacidad empleando los métodos planteados por el FEMA y el ACSE 41-13 se logra ver el desempeño de esta para así poder determinar y dar una valoración en cuanto el desempeño sísmico que está presente así los desplazamientos de fluencia y máximos hasta que se produzca el colapso de la misma.
Los códigos actuales de diseño son cada vez más estrictos para el diseño de las estructuras que necesitan mantenerse operando después de un evento sísmico
The present investigation is determined to evaluate the seismic performance of a 9-level reinforced concrete building, whose structural system is provided with a non-reinforced masonry. Considering the characteristics and properties of the sections and materials that make up the structure, a model was processed through the ETABS program. A non-linear static Pushover analysis was performed where the shear forces and lateral displacements associated with obstacles are determined; In addition, the capacity curve of the established structure is obtained, using this capacity curve using the methods proposed by the FEMA and ACSE 41-13, it is possible to see its performance in order to determine and give an assessment as to the seismic performance that the creep and maximum displacements are present until the collapse of the same occurs. The current design codes are increasingly stringent for the design of structures that have to keep operating after a seismic event
