El cálculo de las estructuras de soporte para señalizaciones viales se realiza mediante la norma AASHTO con la cual se realiza fundamentalmente el chequeo a Fatiga, pero con ella no se llegan a conocer las tensiones von Mises, las tensiones tangenciales ni los desplazamientos en cualquier punto de la estructura. En el presente trabajo se determinan las cargas actuantes, así como sus combinaciones más críticas para el análisis. Se realiza el cálculo analítico a través de los métodos y las normas establecidas para ello y se confecciona un modelo de elementos finitos cuya simulación numérica complementa los resultados obtenidos por las normas. The calculation of the support structures for highway signs is carried out by means of the AASHTO standard, with which the Fatigue check is fundamentally carried out, but with it the von Mises stress, the tangential stress and the displacements at any point of the structure are not known. In the present work, the acting loads are determined, as well as their most critical combinations for the analysis. The analytical calculation is performed through the methods and standards established for it and a finite element model is created whose numerical simulation complements the results obtained by the standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
