Eptisa conducted dynamic load tests in the viaduct over the River Danube between Vidin in Bulgaria and Calafat in Romania

The structure is 1951 m long with maximum lights of 180 m over the navigable channel of the river

Last May Eptisa received a contract from the Spanish company FCC (Fomento de Construcciones y Contratas) for the supervision and conduction of dynamic load tests of the structure of the new International Viaduct over the River Danube, between the municipalities of Vidin in Bulgaria and Calafat in Romania. This viaduct is part of the Corridor IV linking Dresde (Germany) with Istanbul (Turkey) and consists of a bridge with two carriageways for vehicles (two independent lanes) and railway (one track). The structure is 1951 m long with maximum lights of 180 m over the navigable channel of the River Danube.

The activities developed by Eptisa consisted of supervision, conduction and analysis of the data obtained through dynamic load tests with railways before the reception and opening to traffic. As well as the dynamic load tests, Eptisa carried out turns’ control in the critical areas of the platform during the static load tests, by an automated acquisition system which allows measuring rotations with a precision close to 7x10-3 mrad.

Once the tests where finalized, the Technical Office of Eptisa analyzed the obtained data and reported the results, validating the structural behaviour of the bridge.
