Abstract (EN): It is of high importance to develop innovative strengthening and rehabilitation operations for bridges whose design life is coming to an end. A case study concerning the centenary Portela road bridge in Coimbra is addressed. In situ experiments were performed in order to obtain a modal identification of the structure. The data was used to elaborate a reliable numerical model in order to compute and analyse the stress level on each element. It also allowed identifying which elements did not satisfy the strength and stability requirements of current standards. Thereby, the main goal was to propose a structural strengthening scenario, concerning its superstructure, in order to provide the safety levels required with emphasis on prolonging the superstructure, namely concerning the strength, deformation and fatigue resistance.
