Abstrait:

The paper investigates the optimizing criteria for most common structural bridges typologies, with respect of some relevant aspects as the behaviour under static and seismic actions; minimization of overall construction costs; flexibility of the choice of the number and the size of spans in a certain fixed range in relation to the geological and morphological constraints, structural durability and maintenance costs; aesthetic optimization and minimization of the environmental impact. Examples of optimization of prestressed concrete and composite steel - concrete girder bridges are illustrated, which take into account aspects and parameters outlined above.
