Introduction

Assessing the integrity of the structures in real time is a very important topic for which many methods have been developed in the last decades. Today, structural health monitoring (SHM) is gaining more and more attention: in the case of bridges, the maximum loads tend to increase (increase of the vehicle weights), while most of the structures are coming to the end of their theoretical lifetime. In addition, exceptional events such as collisions or earthquakes can cause more severe and fast deteriorations. Optimal maintenance calls for an early detection of small damage in structures, as it is well known that limited and frequent repairs are much less costly than major repairs or total rebuilding after collapse. Current monitoring practice consists in scheduled maintenances including visual inspections, ultrasounds, eddy current, magnetic...
