Title: Prestressed Concrete Bridge Construction
Author(s): Ulrich Finsterwalder
Publication: Journal Proceedings
Appears on pages(s): 1037-1046
Keywords: bridge, construction, prestressed bridge, stress ribbon method.
Abstract:Since 1950, about 90 prestressed bridges have been built using the free cantilever system of construction. The system is described and several projects discussed. A new concept in prestressed bridge construction, the stress ribbon bridge, is also discussed. This system uses a stress ribbon of concrete hanging in a funicular curve cantilevered from the piers at both ends. The stress ribbon concept is equivalent to the steel suspension bridge for concrete construction. While none have been built to date, several proposed bridges are described.
