Balanced Lift Method—A New Bridge Construction Technique
The economic performance of concrete bridges can be improved in certain design situations by using the balanced lift method, a new bridge construction method developed at the Vienna University of Technology. This method proposes to build the bridge girders in a vertical position and to rotate them into the final horizontal position with the aid of compression struts. The compression struts decrease the span of the bridge and allow lighter bridge girders, compared to bridges built by the balanced cantilever method or incremental launching, to be obtained. The balanced lift method can be applied for bridges with high and low piers enabling the construction of bridges over deep or low valleys. The first application of the new method is the construction of two bridges with low piers for the Austrian road management company (ASFINAG) crossing the rivers Lafnitz and Lahnbach on the S7 motorway in the south-east of Austria.
