En el presente trabajo se emplea la metodología de evaluación para puentes existentes planteado por The Manual for Bridge Evaluation de la AASHTO adaptándola a las condiciones específicas del Ecuador y siguiendo lo establecido por el Ministerio de Transporte de Obras Públicas del Ecuador y la Normativa Ecuatoriana Vial. El análisis estructural se enfocó en la metodología de evaluación de capacidad por factor de carga y resistencia, aplicada al caso del Puente sobre el río Vite, ubicado en la provincia de Manabí en el Ecuador, el mismo que en base a la inspección visual de sus elementos se constató un deterioro aceptable calificando cualitativamente la condición del puente. Para la verificación, se aplicaron combinaciones de carga bajo la acción de situaciones adversas con efectos estáticos y dinámicos, prestando principal atención a los efectos de carga sísmica empleando la Normativa Ecuatoriana de Construcción. Para el cálculo de la resistencia real se consideraron parámetros estructurales de los elementos del puente mediante los planos usados en su construcción. Posteriormente se desarrolló un modelo analítico en el software CSI Bridge, para determinar los efectos de carga de diseño. Los resultados se utilizaron para la determinación del Índice de capacidad en las secciones donde se esperaba que se produjeran las mayores solicitaciones, proporcionando niveles de confiabilidad, estabilidad y seguridad requeridas. Se concluye que tanto la superestructura como la subestructura no cumplen los niveles de resistencia según la normativa actual.
In this work, the evaluation methodology for existing bridges proposed by The Manual for Bridge Evaluation of the AASHTO is utilized, adapting it to the specific conditions of Ecuador and following the guidelines established by the Ministry of Transportation and Public Works of Ecuador and the Ecuadorian Road Regulations. The structural analysis focuses on the capacity evaluation methodology using load factor and resistance, applied specifically to the Bridge over the Vite River, located in the province of Manabí, Ecuador. Additionally, through visual inspection of its components, acceptable levels of deterioration were identified, allowing for a qualitative assessment of the bridge's condition. To verify these findings, various load combinations were applied, accounting for both static and dynamic effects, with particular emphasis on seismic loads in accordance with the Ecuadorian Construction Regulations. To calculate the actual resistance, structural parameters of the bridge elements were taken into account based on the construction plans. Subsequently, an analytical model was developed using CSI Bridge software to determine the design load effects. The results were then used to assess the Capacity Index in sections where the highest demands were anticipated, ensuring required levels of reliability, stability, and safety. It is concluded that neither the superstructure nor the substructure meet the resistance levels stipulated by current regulations.
