Abstract:

New bridge construction techniques such as the pre-cast segmental construction method yield special requirements for the design and proof checking process. In the case of stage-wise erection, an exact calculation of the bridge deformations arising throughout the construction schedule - and therefore the definition of the required pre-camber values and fabrication shapes - was for long time an almost insoluble problem.

An appropriate tool allowing for getting the ability to determine the effects of constraining the structure into a certain pre-defined position at any stage of construction has recently been provided. The respective erection control facility accurately controls the position and the forces in the segments in stage-wise built structures. The presented erection control tool also supports the definition of required compensation measures due to deviations from the scheduled position.
