Resumen
El presente trabajo de titulación tiene como objetivo obtener el punto de desempeño de la edificación, a través de la aplicación de 2 metodologías de análisis no lineal: estática Pushover y dinámica time-History. Primero evaluando elementos estructurales existentes con base a los criterios sismo resistentes dados por la NEC-SE-DS y ACI-318-19. Se realizó el análisis modal espectral obteniendo un periodo de vibración de 1.40 segundos. Con el análisis no lineal estático Pushover para un sismo de diseño el punto de desempeño se encuentra fuera de curva de capacidad, esto, por no presentar un mecanismo de colapso deseado. La dirección más crítica es el sentido x con una deriva de 0.016. Con el análisis Times History la dirección x no cumple dando 0.025, se concluye que la edificación no tendrá un buen comportamiento frente a un sismo de diseño y si no se aplica los reforzamientos requeridos la estructura va colapsar.
The objective of this degree work is to obtain the performance point of the building, through the application of 2 non-linear analysis methodologies: static Pushover and dynamic time-History. First, evaluating existing structural elements based on the earthquake resistant criteria given by the NEC-SE-DS and ACI-318-19. Spectral modal analysis was performed, obtaining a vibration period of 1.40 seconds. With the nonlinear static Pushover analysis for a design earthquake, the performance point is outside the capacity curve, because it does not present a desired collapse mechanism. The most critical direction is the x direction with a drift of 0.016. With the Times History analysis, the x-direction does not comply giving 0.025, it is concluded that the building will not perform well against a design earthquake and if the required reinforcements are not applied, the structure will collapse.
