STAYED BRIDGE: COMPUTATIONAL MODELING AND ANALYSIS OF THE SIMULATION OF WIND EFFECTS

Resumo

Cable-stayed bridges can present damage to their components because they are constantly subjected to
the action of the winds. This type of structure was a great advance in engineering, making it possible to build more
economical bridges, as they were able to overcome large spans without the need for several supports or a large
structure in arches. At the same time, it made the problem of wind forces more important, because it is a light and
slender structure, it ends up suffering serious aerodynamic effects, which in more extreme cases can lead to
collapse. Using finite element software, a model bridge located in the municipality of Foz do Iguaçu-PR, subjected
to the effects of the natural action of the winds of this region, was analyzed to verify the behavior of the stays and
the vibrations transmitted by them to the decks, verifying possible ruptures caused by fatigue and the possibility
of the occurrence of rupture caused by the resonance of the components, thus obtaining expected results in terms
of their resistance capacity to a stress situation.
