It implemented the problem of identification of damaged bearing beams span bridge structures using vibration diagnostics methods, taking into account experimental uncertainties associated with natural hazards and man-made processes. Method fault location is based on analysis of dynamic properties of the structure, such as the natural frequencies and mode shapes. The paper shows the study of finite element model of the bridge structure using the method of determining structural damage indicator based on the values ​​of waveforms normalization taking into account the values ​​of the oscillation area.

Keywords: damage detection, multi-girder bridge superstructure
