Resumen
Este trabajo introduce la motivación por los beneficios del enlace del Análisis por Elementos Finitos con los Ensayos en estructuras. En él aparece una aplicación típica en el campo del análisis estático y dinámico de estructuras, específicamente a un puente de ferrocarril metálico. Se aplica el desarrollo de la modelación en el programa SAP2000 para obtención de las tensiones y deformaciones que facilite la definición de tipos de reparación y rehabilitación de la estructura del puente a realizar. Se presenta un procedimiento para la calibración del modelo tanto a través del análisis de sensibilidad o convergencia como por ensayo de diagnostico realizado, de forma tal que mejore la correspondencia entre ambos procedimientos. Se determina el factor de evaluación de los elementos de la estructura del puente para la carga C- 30-7, con el mismo modelo calibrado obtenido, permitiendo así la comparación del elemento con la carga.
This study introduces the motivation for the benefits of linkage by Analysis of Finite Elements with testing in structures. Use was made of typical application in the field of static analysis and structural dynamics, with particular reference to metallic rail bridge. We applied the development of a model with the SAP2000 in order to detect tensions and deformations that will facilitate the definition of the type of repairs and rehabilitations necessary in the bridge structure. We presented a procedure for the calibration of the model through sensibility or convergence analysis much as the diagnostic test earlier realized, such that improvement can made within the two procedures. Factorial evaluation was made of the structural elements of the bridge for weight of C-30-7 train, with the same calibrated model obtained in the study, in order to enhance comparis within the element of the weight.
