Study on Dynamic Detection of Reinforced Concrete Bridge Damage by Finite Element Model Updating

The purpose of this research is to detect faults in reinforced concrete bridges using an MMUM mathematical model updating approach based on incomplete test data. A suitable finite element model of a repaired bridge is created. The diagnostics can be used to locate and detect problems in a reinforced concrete bridge. As a result, modal testing techniques were employed to monitor the progress of analytical predictions. In addition, a finite time centred space scheme has been created to solve a set of equations in a bridge model that can easily accommodate finite element matrices. The approach is utilised in this study to detect damage and existing cracks in a restored bridge in real time. The method was put to the test on a repaired bridge at Oued Oumazer, Algeria. Identification approaches have been proven to be capable of detecting the precise location of damaged portions that need to be repaired while avoiding the finite element model’s mass, stiffness, and loading errors.
