1 Introduction Bridge Health Monitoring (BHM) usually refers to the process of implementing a damage detection and characterization strategy for bridge structures management. [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ] Here, damage is defined as changes to the material and/or geometric properties of a structural system, including changes to the boundary conditions and system connectivity, which adversely affect the system’s performance. Process of BHM can be generally defined as an act of acquiring, processing, communicating and archiving information about the structure
