This paper presents the application of Error-Domain Model Falsification (EDMF) for Finite Element Model Updating (FEMU) to predict a reconstructed Ombla bridge’s response accurately. EDMF has been increasingly favored in bridge engineering for its superior accuracy in identifying and predicting structural responses, particularly when traditional methods like Bayesian FEMU and residual minimization fall short due to significant systematic uncertainties in structural models. The analysis was conducted in Abaqus CAE 2016 using three-dimensional finite elements. Three distinct finite element models were developed to investigate the Gerber joint connection, with each model tested across 15 different combinations of Young’s elastic modulus and density. Out of 45 models, EDMF singled out five potential candidates, all characterized by Young’s modulus of 35 GPa and a density range of 2.4–2.6 t/m3. Upon adding a 13.9 cm slab to these models, the modal parameters were identified, and the expected ranges for the first five natural frequencies were established. Notably, the first three frequencies after reconstruction are anticipated to be approximately 7%, 40%, and 23% higher than those recorded prior to the bridge’s reconstruction.
