Brücken mit vorgespannter Stahlunterspannung
Bridges suspended by prestressed steel tubes. The structural system of suspended girders was used for bridge structures as early as the beginning of the 19th century. Because of the technological advancements in the field of prestressing and due to the high structural efficiency, this structural concept has regained significance in recent years. A promsing application consists of the combination of a simple suspended steel structure with prestressing technology.
