Resumen
En el presente proyecto de titulación se planteará un modelo de análisis sismo resistente basado en el desempeño sísmico para una edificación de hormigón armado de seis niveles más un nivel correspondiente a la azotea, la edificación se encuentra ubicada en Punta Blanca, provincia de Santa Elena.
El método a utilizarse en este proyecto es el análisis estático no lineal AENL “Pushover”, con el objetivo de evaluar el comportamiento no lineal de la estructura sometida a cargas laterales o sísmicas, debido a los acontecimientos suscitados en nuestro país por la alta sismicidad, es por esta razón que se requiere de un mejor análisis donde involucre diferentes niveles de demanda sísmica que predicen el comportamiento de la estructura durante un evento sísmico y los daños que puedan sufrir sus elementos estructurales, donde el objetivo principal mediante este análisis es hacer que las estructuras sean seguras, que cumplan con las exigencias mínimas para salvaguardar la vida de sus ocupantes.
Cada capítulo presenta una metodología explicativa del método, donde se definen cada uno de los procesos fundamentales para el análisis y evaluación de la estructura, que abarca múltiples conceptos básicos necesarios y útiles para entender el método antes mencionado.
Mediante el software Etabs–2016, utilizando los parámetros que exigen las normas y códigos vigentes en la actualidad, se modela la estructura bajo criterios sismo resistentes que nos ayudará con la interpretación de los resultados que obtendremos.
Nuestro objetivo, aparte de realizar la evaluación de la estructura de acuerdo al método, es que el presente proyecto sea de interés para los futuros estudiantes de Ingeniería Civil con la finalidad de que ésta sea una herramienta de trabajo útil para el análisis y posterior desarrollo en estructuras de hormigón armado, esta metodología aceptable permite que al momento de evaluar una estructura el profesional tenga la seguridad de que las estructuras puedan soportar sismos considerables sin llegar al colapso.
In the present degree project, a resistant earthquake analysis model based on seismic performance will be proposed for a six–level reinforced concrete building plus a level corresponding to the roof, the building is located in Punta Blanca, Santa Elena province. The method to be used in this project is the non–linear static analysis AENL “Pushover”, with the aim of evaluating the non–linear behavior of the structure subjected to lateral or seismic loads, due to the events caused in our country by high seismicity, it is for this reason that a better analysis is required where it involves different levels of seismic demand that predict the behavior of the structure during a seismic event and the damages that its structural elements may suffer, where the main objective through this analysis is to make the structures are safe, meet the minimum requirements to safeguard the lives of its occupants. Each chapter presents an explanatory methodology of the method, where each of the fundamental processes for the analysis and evaluation of the structure are defined, covering multiple basic concepts necessary and useful for understanding the aforementioned method. Using the Etabs–2016 software, using the parameters required by the standards and codes currently in force, the structure is modeled under earthquake resistant criteria that will help us with the interpretation of the results we will obtain. Our objective, apart from carrying out the evaluation of the structure according to the method, is that this project is of interest to future Civil Engineering students in order to make it a useful work tool for analysis and further development in for reinforced concrete structures, this acceptable methodology allows that when evaluating a structure, the professional has the certainty that the structures can withstand considerable earthquakes without reaching collapse
