The Rehabilitation of the Historical Bridge of Konitsa: A Documentation-Based Investigation of Structural Behaviour
The Konitsa bridge was constructed in 1869 over the Aoos river. It is one of the most important arch bridges in the Balkan region and the larger in Greece, with a clear span of its semi-circular arch approximately equal to 37,0m. After an unsuccessful attempt of the Ottoman Army in retreat to destroy the bridge by explosives, it was repaired by the French Army the same year 1913 using unreinforced and reinforced concrete. Although the general state of the bridge is good, there is a need for interventions in various areas, including the part that was repaired in 1913.
A detailed architectural and structural survey of the monument, as well as the collection of historical data allowed for significant data to be gathered and interpreted related to the in-time behaviour of the bridge.
In this paper, the methodology applied with the purpose of investigating the structural behaviour of the bridge is presented. To this end, gradual application of loads and actions to the numerical model was adopted, in order to reach a numerical confirmation of the observed pathology. Furthermore, such a procedure has allowed for the assessment of the current state of the bridge, as well as for the identification of the remedial measures that are needed for its protection.
On the other hand, this investigation put in evidence the major significance of exhaustive documentation, as well as the inherent uncertainties related to all steps of this numerical investigation.
