Bridge Dynamic Displacement Monitoring Using Geodetic Measurement

Alexandra Nadia CÎRDEI, Dumitru ONOSE


The paper analyzes the possibility to define a dynamic model associated to a bridge using the results of geodetic measurements made for displacement monitoring using modern calculation models. Combining the results obtained with two modern calculation models (Finite Element Method and Kalman Filter) we can define a complex model, able of meeting current risk management requirements. The paper aims to highlight the importance and usefulness of realizing the dynamic model of a bridge in order to test hypotheses regarding limit situations such as: testing the structure response in case of a flood or in the event of a major earthquake, determining the maximum admissible weight on the bridge without requiring interventions, determining the areas where the bridge requires consolidation work after a certain period of time or after natural phenomena etc.
