The goal of this study is to use an MMUM mathematical model updating method from incomplete test data to detect damages in reinforced concrete bridges. It is carried out a suitable finite element model of a repaired bridge. We can use the diagnostics to find and detect damage in a reinforced concrete bridge. As a result, modal testing techniques have been used to check the progress of analytical predictions. Furthermore, a finite time centred space scheme has been developed to solve a set of equations that can readily handle finite element matrices in a bridge model. In this study, the method is used to detect damages as well as existing cracks in a repaired bridge in real time. The repaired bridge at Oued Oumazer in Algeria was chosen to test the method's efficiency.Identification methods have been shown to be capable of detecting the exact location of damage areas that need to be rectified while avoiding the inaccuracies of the finite element model for mass, stiffness, and loading.
