Resumen
El presente trabajo de titulación se evalúa el desempeño sísmico del edificio de Idiomas, ubicado en la ciudad de Milagro, en donde se aplicaron 2 métodos de análisis, el primero es el análisis dinámico modal espectral en donde se revisó el comportamiento sismo resistente de la estructura, obteniendo un periodo de vibración de 0,65 segundos y cumpliendo con el chequeo de derivas inelásticas dando como resultados derivas menores al admisible que es el 0,02 en todos los pisos, mediante el análisis estático no lineal(Pushover), se obtuvo la curva de capacidad, en donde la estructura es más resistente y tiene mayor capacidad en sentido “X” que en el sentido “Y” donde su capacidad es deficiente, además su punto de desempeño bajo los diferentes niveles de amenaza sísmica resulto en que la estructura ante un sismo muy raro no cumple con el desempeño objetivo, en ninguna dirección.
The present graduation project evaluates the seismic performance of the Idiomas building, located in the city of Milagro. Two analysis methods were applied. The first one is the dynamic modal spectral analysis, where the seismic resistant behavior of the structure was reviewed, obtaining a vibration period of 0.65 seconds, and complying with the check of inelastic drifts, resulting in drifts lower than the allowable 0.02 on all floors. Through the non-linear static analysis (Pushover), the capacity curve was obtained, showing that the structure is stronger and has greater capacity in the "X" direction than in the "Y" direction, where its capacity is deficient. Additionally, its performance point under different levels of seismic threat resulted in the structure not meeting the performance objective during a very rare earthquake, in any direction.
