Acesso em:.https://bdm.ufpa.br/handle/prefix/10154We consider a suspension bridge system of length l where the suspension cables are subject to thermoelastic effects. The theory that mathematically models the small bends in the deck beams is Timoshenko’s theory, which models the deck. We use semigroup theory. The existence and uniqueness of the solution are obtained using the Lumer-Phillips theorem. For the asymptotic behavior presented, under certain restrictions, a necessary and sufficient condition is required to guarantee exponential stability. However, in a specific case, we do not observe exponential decay, regardless of the relationship between the system coefficients; in this case, we prove polynomial decay.Acesso AbertoPonte suspensaViga de TimoshenkoEquações diferenciais parciaisTeorema de Lummer-PhillipsSuspension bridgeTimoshenko-Enrenfest beamPartial differential equationsLummer- Phillips TheoremCNPQ::CIENCIAS EXATAS E DA TERRA::FISICATrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
