Evaluación del Desempeño Sísmico de una Nave Industrial de Acero para el sector minero utilizando el ATC-40 / Evaluation of the seismic performance of a mining steel building according to ATC-40

Guevara Alarcón, Aldo Fernando 05 November 2020 (has links)
El trabajo de investigación se ha denominado “Evaluación del desempeño sísmico de una nave industrial de acero para el sector minero utilizando el ATC-40”, tiene como propósito determinar el comportamiento sísmico de la nave industrial de acero para el sector minero mediante el código ATC-40. La aplicación de análisis estático no lineal como Pushover y Pushover Modal al modelo de cálculo de estructuras existentes ayuda a determinar el grado de daño y el desempeño sísmico. De esta manera, se aplicó satisfactoriamente el análisis estático no lineal al modelo de una estructura existente mediante el uso del software SAP2000, y a través de datos y gráficos proporcionados por el programa, se conoció el nivel de daño para la nave industrial de acero sometida a grandes solicitaciones sísmicas. El desarrollo de esta tesis se divide en siete capítulos: El primer capítulo es de introducción e importancia. La segunda comprende de las generalidades, objetivos generales y específicos del proyecto de tesis; en el tercero se desarrolla el marco teórico para el análisis Pushover; en el cuarto se muestra el análisis estático lineal y no lineal; el quinto comprende el diseño por el método LRFD y su validación; el sexto presenta el criterio de desempeño sísmico usando el código ATC-40; en el séptimo se muestra el análisis de resultados; el octavo muestra las conclusiones y recomendaciones. Del análisis presentado, se concluye que mediante el análisis Pushover se pudo determinar el nivel de desempeño deseado asegurando continuidad para la producción del mineral, de lo cual se puede garantizar que la estructura va tener un comportamiento aceptable ante los 3 niveles de peligro sísmico y no se verá afectada su producción de mineral. / The present research project is entitled "Evaluation of the seismic performance of a mining steel building according to ATC-40" and has the purpose of determining the seismic performance of a mining building defined in the technical report ATC-40. The application of a static nonlinear analysis to the computational model of an existing structure can determine the level of damage and the expected seismic performance. Accordingly, the nonlinear static analysis was successfully applied to the model of an existing structure using SAP2000 software, and through data and graphics provided by the program, the level of damage in the industrial building subjected to great seismic actions was determined. This thesis is divided into seven chapters: the first chapter cover the introduction and the importance of the thesis. The second chapter include the generalities, general objectives and specific objectives of the thesis project; the third reviews the Pushover analysis theoretical framework; the fourth shows the linear and nonlinear static analyses; the fifth includes the design by the LRFD method and its validation; the sixth presents the criteria of seismic performance using the ATC-40 method; the seventh shows the analysis of results; the eighth shows the conclusions and recommendations. From the presented analysis, it is concluded that it was possible to achieve the level of performance desired ensuring continuous ore production, and with this, it can be guaranteed that the structure will have an acceptable behavior for the 3 levels of seismic hazard and that the ore production will not be affected. / Tesis
