In this paper, we study the indirect stabilization of a coupled string-beam system related to the well-known Lazer-McKenna suspension bridge model. We prove some decay results of the energy of the system with either interior dampings or boundary ones. Our method is based on observ-ability estimates of the undamped system and on the spectral analysis of the spatial operator.
