Resumen
En esta investigación se evalúa el comportamiento dinámico y estático no lineal “Pushover” de una estructura de 8 niveles ubicada en la provincia del Guayas, ciudad de Guayaquil, de uso residencial multifamiliar. Se planteó una propuesta estructural para la cual se realizó el diseño con secciones mínimas por medio del código ACI318-14 y las NEC-15 para evaluar las derivas máximas permisibles. Se desarrollaron dos modelos estructurales en el programa ETABS, incorporando en uno de los modelos disipadores de energía a fricción de la empresa fabricante Quaketek Inc. Esta edificación es sometida a un sismo de diseño mediante una simulación en el software, a través del cual se analizaron sus comportamientos como periodo, masa participativa, modos de vibración, cortante de piso, además se obtiene la curva de capacidad, el punto y niveles de desempeño de acuerdo al FEMA 440, como también el trabajo que producen los disipadores.
Palabras Claves:
In this research is evaluated the dynamic and static nonlinear “Pushover” behavior of an 8-level structure, located in Guayas province, Guayaquil, of multifamily residential use. A structural proposal was posed for which the design was made with minimum sections by means of the ACI318-14 code and the NEC-15 to evaluate the maximum allowable drifts. Two structural models were developed in the ETABS program, incorporating one of the friction dampers models of the manufacturing company Quaketek Inc. This building is subjected to a design earthquake through a simulation in the software, through which they were analyzed their behaviors such as period, participatory mass, vibration modes, floor shear, also the capacity curve, the point and performance levels according to FEMA 440 are obtained, as well as the work produced by the friction dampers.
