Abstract
The balanced lift method is a building bridge method that was developed at the TU Wien. The most common methods to build bridges are the ones using falsework or the cantilever method, but a rather uncommon method, the lowering of arches is seen as the origin of the balanced lift method. The idea was to create a method which would allow a bridge to be built in a very fast manner without the usage of falsework, using prefabricated elements and mounting all parts together in a position – in this case vertically – that would simplify the construction process. In order to reach the final state of the bridge, the vertically assembled parts are rotated into their final horizontal position. This article contains a description of the development of the method, a large scale test will be portrayed and an already designed bridges using the balanced lift method will be shown.
