Performance of Concrete Segmental and Cable Stayed Bridges in Europe

FHWA-PL-01-019

The main objective of the scanning activity was to evaluate the European inventory of prestressed concrete segmental and cable-stayed bridges. On average, European structures are a decade or two older than similar ones in the United States. Members of the scan team examined durability; identified possible future needs for maintenance, repair and retrofit, and replacement; and compared trends and current practice.

The team visited four countries: Switzerland, Germany, Denmark, and France. Representatives from Norway and the United Kingdom also met with the team.

In general, segmental and cable-stay technology and developments in Europe and the United States are moving in parallel directions. Early performance problems from the 1960s and 1970s have been eliminated through new codes and practices on both sides of the Atlantic. Technical advances continue to be made with respect to corrosion, external and internal prestressing tendons, inspection methods, use of new composite materials, and construction techniques.
