Cet article est consacré à l'étude d'un problème semi-linéaire décrivant le déplacement vers le bas d'un pont suspendu, en présence d'une force de rappel exercée par les câbles, une force extérieure qui tient compte de la gravité et un terme de retard qui représente l'historique.

Le but est d'établir un résultat bien posé et l'existence d'un attracteur global de dimension finie.

This paper is devoted to the study of a semilinear problem describing the downward displacement of a suspension bridge in the presence of a hanger restoring force h(u), an external force f which includes gravity, and a delay term which accounts for its history. The goal is to establish a well-posedness result and the existence of a finite-dimensional global attractor.
