Bridges are an integrated part of the transportation infrastructure, which usually applied to severe working environments. Thus, bridges require a continuous screening for their structural health. Recently, there has been an intensive work in the field of monitoring the structural degradation of the bridge structures, yet the developed approaches focus on identifying the existence of the damage with no clue about the damage severity or location. This paper introduces the use of the Frequency Domain Decomposition for the identification of the damage severity and extent. The Frequency Domain Decomposition is used to estimate the mode shape of the bridge using a few measurements on the bridge structure. The differences in the mode shapes between the healthy and damaged states of the bridge are used to identify the damage location and extent. The approach will be verified numerically under the presence of random noise in the input signal. The approach will be extended for a two-dimensional steel frame. The simulation of the vehicle-bridge interaction and the dynamic simulation of the steel structure are performed in MATLAB.
