The surveillance of civil engineering structures has become increasingly important over the last decade. Nowadays, several methods and means of Structural Health Monitoring (SHM) exist. They help detect, localize and quantify damage, and predict the remaining service life of structures. One of the major challenges in the SHM field of civil engineering structures is to define a global and reliable methodology of damage detection and localization. In this paper, a complete chain of surveillance is set up on a three-dimensional Finite Element (FE) model of the Canadian Rivière-Aux-Mulets bridge, created with the ABAQUS software. The structure is damaged by a true seismic signal and a set of Vibration-Based Damage Detection Methods (VBDDM) is applied to detect and to localize the damage.
