Resumen
En este trabajo de titulación tuvo como objetivo de evaluar la vulnerabilidad estructural de dos Edificios Educativos ubicado en el cantón Echeandía provincia de Bolívar en donde se aplicó la metodología del ASCE/SEI 41 – 17 usando el espectro de respuesta de la normativa NEC-SD-SE para determinar si los diseños estructurales cumplen con los requisitos establecidos en el criterio de aceptación. Para la evaluación de los dos Edificios Educativos se realizó una inspección visual del estado actual de sus elementes estructurales y no estructurales, mediante con esto se procedió a realizar los modelos matemáticos en el software ETABS para cada institución considerando las combinaciones de cargas estipulados en el ASCE/SEI 41 -17 y la interacción Tabique – Pórtico de la norma técnica E.70 para que aporte rigidez lateral en el diseño.
Una vez ejecutado los dos modelos matemáticos, se compararon con el modo de vibración para verificar el comportamiento de las dos estructuras y con las demandas obtenidas de cada elemento estructural se obtuvo los DCR para vigas y columnas. En vigas se calculó la flexión y fuerza cortantes mientras que en columnas se analizó por flexo-compresión y fuerza cortante.
The objective of this degree work was to evaluate the structural vulnerability of two Educational Buildings located in the Echeandía canton, Bolívar province, where the ASCE / SEI 41 - 17 methodology was used using the response spectrum of the NEC-SD-SE to determine if the structural designs meet the requirements established in the acceptance criteria. For the evaluation of the two educational buildings visual inspection of the current state of its structural and non-structural elementes was performed by with this he proceeded to make mathematical models in the ETABS software for each institution considering load combinations stipulated in the ASCE / SEI 41 -17 and the Partition - Portico interaction of the technical standard E.70 to provide lateral rigidity in the design. Once the two mathematical models were executed, they were compared with the vibration mode to verify the behavior of the two structures and with the demands obtained from each structural element, the ratios D/C for beams and columns were obtained. In beams the bending and shear force were calculated, while in columns it was analyzed by bending-compression and shear force.
