"Apart from durability, the most important factor in the whole life design of reinforced and, in particular, prestressed concrete bridges is the Serviceability Limit State. From this point of view. prestressed concrete bridges are very sensitive to long-term increase of deflections. This phenomenon has paramount importance for serviceability, durability and long-time reliability of such bridges. This is why a reliable prediction of deformations of bridges during their construction as well as duringtheir service life is extremely important. The principal significance of the proposed project for bridge design practice consists in that the results of the appropriate solutions and the developed analytical and design methods will help creating the sufficient theoretical tools for reliable and economic structural design of prestressed concrete box girder bridges while respecting random character of input parameters, enabling great economy of materials, energy and costs and their better utilisation"@en .
